Gamebooster causing Send Error Report?

Greetings, Cross-shooters. I recently (one hour ago) installed "Gamebooster." The reason I have done so is my FPS is lower than an Orangutan's tits, and I want to increase it a little. The game starts up perfectly fine, I can log in and whatnot, enter a server, and join a game. Once the loading screen begins for the map, the screen freezes and about a minute later it asks me to send an error report. I have already tried to run it in compatibility mode, and it doesn't work.

Please refrain from telling me to uninstall and reinstall, not use Gamebooster, or restart my computer, for I know for a FACT those are not the solutions. I CAN join a game and play without Gamebooster, but my FPS is shit. Is anybody experiencing the same issue? Are there any known solutions? Thanks!

Did you check whether or not gamebooster was seeing the crossfire client as a virus?
If not then check the white listing list within the gamebooster menu and try to add it to the bypass list.
