So lately I've been having many issues with the game.
First was the ATI card problems, I downloaded the hotfix but nothing happened (AMD 6850)
Then there was a problem with starting the game, it would show "BRINK" and close without an error message. I tried fixing this by renaming the "assets" folder, it worked but then every second game i would play the game would crash,
Next was a problem with joining servers, the game would just crash.
I redownloaded the game and it still doesnt start. Renaming the folder doesnt fix the connection problem and crashes,
I need help solving these problems.

Specs
-AMD X6 1090t cpu
-AMD Gigabyte 6850
-4GB DDR3

Did you verify the integrity of your game cache in steam?

yeah, when ever i changed the name of the assets, it would download new files in the renamed file.
I tried it many times but nothing seemed to change.

Did you try using the tool that completely removes any traces of the graphics card drivers and reinstalling. I mean, if I was you, at this point I'd just fdisk and go with a fresh install, but most people would try to clear out drivers first.

What tool would that be? I still cant launch the game properly, the only solution if found was changing the asset file but i still cant play. I'll try reinstalling drivers

I tried changing the file name again and i can play 1 game, and anything else the game will crash. i still have the graphical issues, and the crashing
