For some reason i have to keep reinstalling flash player to view sites. One minute its on my pc and the next it says flash player needs installing to view this site. I run advanced windows care,Ccleaner,Winaso registry optimizer and Eusing registry cleaner all free ones every now and again. Could it be one of these that is removing flash? And should i be ticking or un-ticking something on one of these programes that i don't know about. THANKS.
