Shoot problem

I go in game. Short fuse, 1v1 elim.
All the textures removed with rez chams.
Lowest graphics, gamebooster on, and now that the fps is up, I can't fucking shoot.
Any help? Similar experiences?
The mouse works everywhere except ingame for shooting. I can still aim.

Either Reinstall CA.. Or take of all the boosters and see if it works. if it does, don't use them

Make sure you fire key hasn't changed. Mine changed out of the blue one day >.<
