Hi like alot of people i tried and tried to get this game to work and countless times got the “brink has stopped working” but i finally suceeded in getting it to work and this might help you aswell. First my card is a radeon HD 4650 1gb and my operating system is vista so i installed the 11.5a hotfix rc3 drivers for vista users with desktop graphics use the vista fix that is out or it wont install and obv update c++ package and direct x. Then i still got the error however i read that portal 2 caused alot of people the same error because AIM was running in the background, i however do not have AIM but i went to task manager and shut down any unecessary programs such as google toolbar, punkbuster and a couple of others, i havn’t figured out yet which was causing the game not to launch but once i carefully checked through the task manager and closed the programs not needed the game now launches and plays beautifully. I dont know if this will work for everyone but i tried everything else and this done it for me so try for yourselves Thanks:D
EDIT: ok sorry not a permanent fix seems lsass.exe is causing this crash on vista if you close the process the game will work but your computer will eventually restart as it is an important process
