Invalid STEAM UserID Ticket Fix
Looks like Valve accidentally broke something on their end for source modifications, here's a known fix to help you guys get back in game asap!

1. Completely close Steam.
2. Delete ClientRegistry.blob in your Steam Directory
3. Run Steam.exe.


An alternative way to fix the issue if the first method doesn't work:

1. Exit Steam if you haven't already.
2. Delete the config folder in your Steam directory.
3. Run Steam.exe
- Steam will redownload all of the files you deleted and verify the contents of your steamapps folder. (Credible sources say this process only takes a couple minutes)
4. Test the game!


Another way:

1. Completely exit Steam
2. Head to your Steam folder and delete everything EXCEPT your steam.exe and Steamapps folder
3. Run Steam.exe


Please let us know if you're able to fix this problem! If you've found another method that fixes the issue, post it here!

First 2 didnt fix this for me.. I don't want to redownload all my games and reinstall steam. Is there another fix for this or is this game broken now forever w/o any reason.

I just tried all three methods and none seemed to work. If the problem is affecting all mods, then we should expect a fix from Valve these coming days.

Valve are now aware of this issue and are working on a fix. This is an issue on their side, and I'm not aware of any 'fixes' in the mean time'.
