what do you mean no buttons in-game have ever changed . F11 & F4 turn on ? F11 is for the zoom feature and i some times experince a bug with it not alowing me to zoom in or out but usauly fixes it self after a couple moments and rage pounding the key ^_^ and F4 is for fire mode control and ive never had an issue with that other then forgeting to push it to change fire mode when in my SS

Try resetting them in the f10 menu

Lol that triggers the Frigate Automatic function.

I'm going to try reinstalling and hope its fixed. I also had to replace the HShield folder because of an error, maybe that's the problem?

I doubt it has anything to do with hs since that wouldnt control any of the ingame stuff.
