Hello I'm using the dowloaded free version of Swift. I downloaded it and just startted using it today. I was able to convert several files from wma to mp3, successfully. But now, every wma file I try to convert to mp3 produces the following error message; "Conversion of the file has failed". I removed and reloaded Swift twice, thinking that there may be a software glitch, however I continue receiving the same "conversion has failed" message in the "other information" box of the Swift program. Any suggestions would be appreciated. Thanks, C.
