Media Player Problem

I cannot copy CDS. My Operating System is Windows XP. I can no longer copy CDs to the hard drive with either Media Player of RealPlayer. The last time I coped a CD was several months ago. I recently updated Media Player to Version 9. However, I do not believe that to be the cause of the problem - but I really don't know. I have done a System Restore to pre-version 9 with no effect. The error message in Media Player reads: "Windows Media Player has encountered an unknown error". There is no error number or ID. I do not have any earlier System Restore points. I am not aware of any other problems with my system. I need a fix which will make Media Player fully functional. Do I need to re-install something? I don't want to lose all my files. I need help now, please. Please advise if more information is required. ## Deliverables This project will be complete when I have received and implemented a fix to the problem described above.
