User Account control is set too high on the machine, you'll have to turn it down a bit.

Control Panel - User Accounts - Change User Account Control (in Win 7)

If it is set to high it blocks a program called ^STOM.EXE which is used to import audio and to change audio format. Turning it down one notch will cause windows to ask your permission to let it run.

Turning it down even more will allow it to just run when called.
I have it down one notch from the top.


I do not work here, but the benefits are still awesome
