Mumble won't work

[caesars salad]

After installing PR2 I have tried to configure mumble but nothing I try works. Each time I select the "option" and then "launch" (for mumble) it immediately crashes. Nothing I do will allow me to configure mumble. I have uninstalled PR2 twice and still no change.

Any idea what's going on?
I'm running Windows 8 and so far this is the only technical issue I've run into.


Thanks
