Mumble can be opened through the option's menu on the launcher, however it does not open automatically when I'm trying to play the game itself.
I will note that I do have another version of mumble installed (I use it for other groups regularly), and using a mumble:// reference pulls my newer version up without issue, though it seems that the game isn't attempting to do so since there are no new instances of any of my mumbles opening (regular + PRMumble.exe). I also do not see any of the separate installtion's settings being opened up in PRMumble, so I do not believe this is the issue.
Everything's set to launch as admin, I've tried toggling compatibility on everything for Windows 8 and Windows 7. I've reinstalled multiple times to both the default Program files directory and another HDD. I've tried manually launching mumble first, launching mumble after getting to the main menu, launching mumble after connecting to a server. Nothing seems to be working for me.
My antivirus is disabled while trying to do such (ESET Smart Security/ Nod 32), and everything in the PR directories is excluded from scanning regardless.
My DirectX is up to date. My .Net 4 is up to date.

I found a thread on reddit that described the same issue, however their go-around for it (connecting to a server, then disconnecting, and then connecting again) did not work for me.
