Unable to Encode Files in the Selected Format

[LCDHD]

I downloaded the trial version of Switch, and it worked perfectly, translated my WMA files to WAV files. I purchased it this morning, and now it tells me that it's Unable to Encode Files inthe Selected Format, even if trying to again convert the WMA files I successfully converted yesterday. Anybody else have this issue?

hmm thats certainly an interesting issue, what happens when you load the file(s) into WavePad? (http://www.nch.com.au/wavepad)

 

Also do a right-click on the file -> click "Properties" -> if it has a "License" tab its probably protected by DRM

 

Just to be clear, nothing changes in the software after you register it, it stays fully-functional both beforehand and afterwards.
