These are simply the things I have found thus far.
Flash player was the first thing I checked; I've accidently changed the settings before, so it's not a new thing.
Besides, when flash player is off, youtube tells you so. When I say youtube videos do not play, I mean that the video remains black; no sound, seek bar, etc. Just a black rectangle. As for the games, the page just remains blank, as does the email.
So please, if anyone can help me I would be very happy. My only guess as to what has happened is that a family member got on the computer and accidently messed something up (Although there is a large chance they messed it up deliberately)
Now, I tried to download the adobe flash player, but it wouldn't even dowload--no pop up blocker notification, nothing. I still believe that this is an unuasual problem-- it's not flash, and probably not adobe.
Please help ASAP!
