So I installed all installation files, including the Mumble in the .97 version (0.6 Beta) and then installed the .97 to .981 upgrade and I get this error.

Steps to reproduce:
1. Install all installation files as usual. When you get to the 'Update Punkbuster' part, do not select the ticks.
2. Run Mumble
Cause: Maybe the new mumble for 1.0 Beta screws up your profile, and thus it cannot connect to the old versions?
Solution that worked: Use a new, or different profile.
Reason: Maybe I was banned on the mumble server?
Issue 2: Failed to create communication with overlay at MumbleOverlayPipe
Cause: Upgrade doesn't properly replace Mumble from 0.6 Beta to 1.0.0 Beta 4.
Solution: Uninstall old version, Install PR 1.0.0 Beta 4.
Steps to reproduce:
1. Install all installation files as usual. When you get to the 'Update Punkbuster' part, do not select the ticks.
2. Run old version of mumble.
