After computer CTD Push to talk in mumble not working

Hi, maybe someonecan give me a clue.
Everything was working fine till I had a computer crash/freezup whilst playing.
Now the buttons have no effect.
I allready tryed remaping them (Putting in the shortcuts fresh) wich works just fine. Only mumble doesn’t open the mic when I press said button.
I even remaped a simple new key to “Push to Talk” but also that won’t work.
Do I need to reinstall mumble?
Thanx for reading!

I would reinstall Mumble.

okay, found the problem. Windows didn’t find the mic anymore even though it was pluged in. Typical : “switch it off and on again” (in this case unplug, replug)

cheers
