Switch won't convert .wma file

[rosindabow]

I have a couple of .wma files that I have tried to convert. I have attempted to convert them to .wav, .aif, and .mp3 - nothing is working. The program crashes each and every time. Switch used to work perfectly - not sure what is going on. I'm running a MacBook Pro, OS 10.5.8. Switch is the latest version - v1.50 Intel. I've tried sending the outputs to different locations - however, all the locations are on the same hard drive as I do not have access to an external hard drive at the moment (not sure if this would affect the conversion process.) I dumped my version of Flip4Mac after reading a thread stating that was causing problems. Any thoughts?
