Thanks for your response. I tried rebuilding my desktop. I was very encouraged when the first sample I launched worked fine but after that the problem came back. It wasn't a problem at all for a long time, just started one day. Does it have anything to do with the amount of music I have downloaded (25 songs) - a memory issue ? Or is it something that is being experienced by others lately ? I miss being able to launch a small portion of the song to see what it really is. Any more ideas out there would be appreciated.
