Please help, i am a CCleaner virgin and im afraid i did something wrong while apparently "fixing selected issues" in registry to do with activeX because for some reason i cannot view videos on youtube etc. I have downloaded the latest abode flashplayer and shockwave but when i try to view a video clip all i get is a blank white square whre the pic should be with a red cross in the top left hand corner. I have followed all support guidelines about abode flashplayer thinking it was the problem but no help. I haven't been on youtube for months so dont know how long i have had this problem but do recall running CCleaner and deleting several errors to do with activeX without backups. I have tried restoring my computer to a previous date in februaury but this has not solved the problem.
