Computer Problems Since Tuesday May 13

I've been having allot of problems since the Guild Wars update of Tuesday, May 13, 2008. I've had a large amount of lag since than and just this past week, my computer has frozen up and crashed three times due to Guild Wars. Each time my computer crashes, or the game shuts down and I try and reopen it, I get a Guild Wars window to pop up that says: Repairing Data Archive. Is this problem just related to my computer, like I have bad memory or some thing, or is it that more people have been having this problem too? Any body know what's going wrong?

Microsoft released updates that day. I would take a good look in that direction, boy-o!
