Trying to burn songs from my computer to a CD-R. Apparently I removed the 1st CD when it was only 99% finished. That was hours ago. I have shutdown which required that I "force Media Player" to shutdown. Now when I try to burn another CD I get this message: "WMP cannot burn to the disc because the drive is in use. Wait a few minutes for other burning tasks to comlete & then try again." I've waited hours. I've forced a shutdown. I've restarted and shutdown again and left my PC off for about 10 minutes. I've reinserted the CD that was 99% finished when I inadvertently removed the CD. I've tried a new CD. I've tried to reburn the same tunes. Also, there is nothing on the CD at all. Thanks for your help.
