Game Not Launching
I bought this game about a year ago and finally decided to play it so I installed it. When I tried to launch, the game loaded for a second then crashed. I tried restarting steam and launching it through the ubisoft launcher instead and it does the same thing. I tried running as administrator and the same thing happens. My ubisoft account is now temporarily banned because of multiple unsuccessful launches which I didn't even know was possible. It's not like I was trying to login to my account with the wrong password, I was just trying to launch a game. I've looked up solutions to no prevail and now I'm here. Does anybody know how to fix this or have any suggestions?

Check also the site from Ubisoft.
There are errors listed being investigated and I did see upon checking mentioned that they close down 6th of may for maintenance or something.
Perhaps it's related?

Edit date was wrong

Sometimes u have to wait for a while when it seems it isn't reacting. It is because probably your pc has issues with connecting to uplay.
Re-installing Uplay works for me. But after one launch I have the same issue and have to wait for a longer periode (>30secs sometimes). After that it will pass the multicultural message and launch the game

You mention that you've tried running the game as administrator, but have you tried setting the compatibility mode also? Try running it in Win 8 compatibility mode or I've even heard of earlier ones working for some people.

- Go to your Assasins Creed 4 Black Flag game folder (Steam\Steamapps\Common\Assasins Creed IV Black Flag)
- Right click AC4BFSP.exe
- Select Properties
- Select Compatibility
- Under "Run this program in compatibility mode for"
- Choose "Windows 8"


or try win XP or even win 95 (I've heard of that fixing it for some)

No it was just temporary but it might happen again if I try to launch the game too many times through the ubisoft launcher

I've found the reason of this issue.

IF u have installed AC:BF through steam, then u should never launch the game through Uplay, nor login into UPLAY for that matter before launching the game.
This will make the game inable to connect to the Ubisoft servers, which also leads to a slow start (lag/freeze into the starting screen which says 'this game is made by a multi-cultural team' -> launch after a minute or so waiting).

If u launch the game through steam, without being logged into Uplay, then Steam will make sure u will launch the game in a correct way, and the game won't freeze beforehand.
Also setting the game to launch into compatibility mode might be a necessity beforehand.

How do I launch the game without having to login to Ubisoft? I have signed out of ubisoft and unlinked it from my steam account but it still requires me to sign into ubisoft to lauch it.
I think he means, when you run it from Steam, it automatically also makes connection with Ubisoft. This is the case with me for this game and for instance also for Rocksmith 2014. But it would need your credentials. Whilst in the game you can then acces uplay just like you can acces Steam overlay if need be. When the servers of Ubisoft are not found, or I just have a bad connection I get an extra error/login screen in Rocksmith from uplay.

But I have also linked my steam account within the Uplay app for pc.

One thing to note, if you go to the admin site of ubisoft for instance to change your password, and if your browser is blocking third party cookies it might not work. I found that some time ago. Changed it like 10 times, but it never happened until i tried that.

I have also (other) problems with uplay, recently they have an updated version, which solved my problem BUT introduced a new one..... Then they advised me to uninstall uplay, reboot and reinstall (making sure you have a copy of your saved files).

That didnt help unfortunately, but an idea for you may be to rename the cache folder in Uplay and then restart it. It should make a new cache, (and if not you still have the backup)

With a normal install it would be here C:/Program Files (x86)/Ubisoft/Ubisoft Game Launcher)
- Rename the folder to cachebackup and then restart uplay.

Unless they fixed it, the steam DL of this game included a outdated version of Uplay. If your DL tried to install that outdated version, it may have corrupted your Uplay app. To reinstall Uplay

Renaming the cache didn't work :(

I have tried uninstalling and reinstalling before and I just tried again with this link but it still didn't work.

Have you registered your product key code for this game on your Uplay account?

With steam app open- game list- right click on AC4 and chose ‘view CD key’.



Any chance you have more than one Uplay account?
