I have had my computer for 4 years now and with Adobe Flash Player installed I have had no trouble viewing videos etc. However, recently I have been unable to view videos and it keeps telling me that I need to download Adobe Flash Player. Even though I thought this was already on my computer, I go ahead and download it. It tells me I have successfully downloaded it. But I still can't view videos. It KEEPS ON telling me I need to download Adobe Flash Player. Anyone know what's going on???
