It is now around two weeks that I receive this message on a blank page when I run some CD-ROMS that have got some video clips on them. I tried the windows installation disk's video clips and I received the same message. I did not have this problem before. It might have happened after running a program that deletes the unnecessary .dll files. This program has saved all the discarded files on a directory now. Also I might have unintentionally deleted something myself and the program may not be the culprit after all.
What should I do?
