OK, so that means there's something weird about the MP3's you are trying to use.
Here's 1 clue - many MP3 software players will CHANGE the file after/during playing it. So the problem is now, that Sonic Stage does not like the file changing behind its back.
Here's a second clue - it's possible that conversion of ANY kind is failing because you need space (specified in Sonic Stage configuration somewhere. Now you know what you're looking for, I am sure you will find it). on the HD to store the temporary "optimized files" before sending them to the NetMD. It may well be that there is no room, or permissions are wrong, or (most likely) the location specified there simply doesn't exist. Try checking that, and pointing to somewhere that does, that you have permission to write to. Note, SS should always be run by an administrator (or at LEAST Power User) because of the permissions problem.
