Hi, this error just came from nowhere. When I double click mumble the send error report screen comes up first, then the mumble window which makes my mouse lag and gives me this crash report

Attempting to use the 1.2.4 client instead of the 1.2.3

I am still getting the following:

Mumble DXGI Window: mumble.exe - Application Error

The instruction at 0x0020cb5c referenced memory at 0x0020cb5c. The memory could not be written. Click OK to terminate the program.

I can sometimes get the client to run if I run as administrator and load it in Windows XP SP3 mode, and various sound options become unavailable by default.
