Stephen,

Try clicking "Go to Folder" in the context menu. This should open a folder that contained the original MP3 files. Does any MP3 file start playing when you double-click it in the folder?

1) If it does not, then the problem is in the system and not in OrangeCD, and can be resolved either by reconfiguring or reinstalling RealPlayer.

2) If the files start playing when you double-click them, then it could be more serious problem. Can you try the item 1 first?

Thanks
