Sorry for not replying quickly.
Can you go into the games folder on your PC and right click the .exe file or the one that starts the game, and then select properties and when the new window pops up can you goto the tab "details" and find the game revision number there.
Make sure you select the trainer that matches the version number of the game.
Dear Mod DABhand . Your tips was successfull because i saw that my game version is different of the trainer so
my version of brink is 1.0.23504.48064

so can u do me a favor please and told to the holder of the lastest version of the brink trainer to update the trainer to fit my uses please (and the uses of the community of course) thx in advance of your effort to contact the concerned one
