Windows XP Home SP2, WMP 10. I did a repair install of XP at the weekend to correct one or two niggling issues. However, on trying to playback some previously downloaded music, I get the error
"Windows Media Player cannot play, synchronize, or burn a protected file because an error occurred while verifying the license." - referred to as C00D11DA on the MS site.
I've tried reinstalling WMP and re-downloading the songs but keep getting the same message. I've also tried restoring the Licence Backup folder from a recent backup, which hasn't helped. Could the licences be corrupted? Obviously, I don't have any useful restore points now. I also didn't realise I was supposed to back up the licenses on a regular basis.
