Mumble instant crash

[wambambola]

Heres the thing, i had some serious mumble lags. Restarting did not fix problems. Still had lags, i could not hear others, they could not hear me, push to talk button got "stuck" and so on.
I tried some solutions i found here, but something happened and i can not launch mumble at all now. I start PR launcher, go to options, launch mumble and after few sec. it crashes. When i tried to play, mumble auto restarts, but after that, it crashes again and it goes on and on and on.

1)I thought i tweaked some settings and it changed something and my mumble went nutz, i have no idea on how to reset settings.
2)I may be confusing something, but i did buy a new mouse, it is Trust gxt 158 i think and i thought i saw something about this screwing up mumble somewhere. Maybe software or idk.

Any ideas? Solutions? Can i provide further information?
