I have basically the same problem as jhob's girlfriend. I had previously backed up my entire SonicStage library (using Windows Backup) to an external HD. After rebuilding my PC, restoring the library, and installing SonicStage CP 4.2, I cannot play any of my .oma music files. I tried re-converting them leaving the "Add copy protection" box unchecked: I receive the following result: SonyMDCM_HikaruRedHot.mpg There's got to be a way to get around this. I have a difficult time accepting that I must re-load all of my CDs. Any assistance would be much appreciated. Thanks...
