EDIT: i Solved the problem with possibly all the Munging Errors on my Windows 7, this might help others too;

I Found out, that if all Munge-CMD-Windows crash right after starting, a possible sollution might be Stereo Mix being deactivated (wow, i feel real dumb)

So, if anyone else has Problems like this, or any munge errors at all, see if Stereo Mix is Deactivated (Right-Click Volume Control, click Recording Devices, then right click Stereo Mix and click Activate - on a side note: if you cant see the Stereo Mix, tick the box for "Show Hidden Devices")

Off-Topic: YAY ^ ^ I Can Start Modding Again!

do you mind posting the actual error?
you can get missing bracket errors for many things such as typos in odf, req or lua and tgas and mshs that visual munge doesnt understand.
