WariYou wiped your mumble certificate, which servers use to verify your username on servers where you registered your name
(Icon looks like: http://puu.sh/gOqwZ/91a7a8dbdd.pngnext to your name when you register somewhere).
There's not much you can do apart from using a different username, or having a mumble server admin unregister the username you used before.
For future reference, you can backup your mumble certificate by going to Configure > Certificate Wizard then Export current certificate, then save that file somewhere safe. You can import it from the same wizard later.
