Exception - Program will be terminated Help

[duke dunac]

So I was in the editor yesterday making a map, which was made using assets from the vanilla game and the Planetside 2 mod found here:
http://store.steampowered.com
Then, I saved it under the name of the map template that it was on. I obviously want to have the template as well, so I saved it as another map with a different name with the intention of clearing it again then saving the template.

Unfortunately, when I tried to save it as another map, the game crashed and gave me an Exception error.

No problem, right? Just reload the Editor and start again, as usual when the game crashes. WRONG. I get the same error when loading the editor.
So, after this, I try to read the error but it's totally indecipherable except for one part at the bottom, which has to do with version 3.251.0.
Because I loaded the Planetside mod, I thought it would be wise to check out the mod.info file which contains version info. I have to edit this file slightly (a one character change in the Max Version line) to run the mod with the current version of the game.

So I changed the file back from its playable state to its non playable state and start up Men of War Assault Squad 2 (NOT the editor) to disable the mod and try to figure out what's going on..

Except, to my despair, the game crashes while in the pre-launch window that shows the game title and gives me the same Exception error.

Of course, now the obvious thing to do would be to uninstall the game, which I promptly do. I also make sure to delete the folder in Common that contains all mod files and created maps- the game is now installed in a completely blank state, with no modded information. Just to be sure, I verify the cache after reinstalling.

I then start up the game and get this exact text, (probably) to the letter.

Which makes absolutely no sense, considering I did a clean reinstall, booted from steam, verified the cache and had no mods preinstalled through workshop.

I'm stuck, and I'd appreciate a bit of help

Please try to launch both Steam and the game as admin.

You can locate the exe here by default
C:\Program Files (x86)\Steam\SteamApps\common\Men of War Assault Squad 2

Right click on it and chose "Run as administrator".

That worked! I can't believe it was that simple.
Besides that, though, do you know why the trigger for this type of error was me simply saving a map in the editor?

Also you're the one who makes map packs right? Love your work tbh
