I'm guessing running it through a virtual machine didn't help - audio processing tends to be a relatively intensive task (though perhaps my computer is just showing its age...)
However, it's not necessarily the only problem. Am I correct in assuming that you are trying to run it from Windows, hence the VMing? My personal recommendation would be to install Linux, but then again I would recommend that for almost any Windows-related problem
'tis what comes of indoctrination, I'm afraid...
