Total Video Converter

I bought this to convert mp4 to WMV. Does not work properly, I have tried many different settings but all the videos come up corrupted in some way. Jumpy video with artifacts. They are not usable, and hence neither is this program. Any way to get my money back? It says it converts to WMV but it does not!
