Computer gone nuts.. lol

Hi,

About 2 weeks ago, I started getting an error when I tried to open “Picasso”, CBlock err=11. Anyway, in properties, there is no shortcut keys either! And realized many programs are doing the same thing, not coming up and no shortcut keys, nothing! Does anybody have any clues on what could have happened, or what I can do about all this mess? I’v taken out 3 programs already, and it’s ridiculous. Oh, on another note, is everybody else having probs getting “images” in g-mail to show up, at least when I would ” push show picture ” it would, now never, nothing. Agghh! I’m screaming with all this mess. Help???!!
