I upgraded from Anydvd 184.108.40.206 to 220.127.116.11 When the upgrade finished, the system asked me to instal a DVD drive. I rebooted the system....that didn't help. I did a "Restore Point" w/Windows XP Pro.......that didn't help. I did a "Repair Instal" of Windows XP Pro.......that didn't help. Finally, I had to do a complete Windows XP Pro install....finally that worked. I also had to reinstall every program & patch to get my system working properly again. I'm afraid to reinstall Anydvd. Any suggestions??
