I'm having the exact same problem the OP is having and I've tried everything he has w no luck.I'm trying to play Farmville on Facebook and it'll let me play for about 10 mins, then crashes. You mentioned they're trying to force us to get HTLM5 (?). Idk what that is, bc I'm very pc illiterate, but I'd really like to know where to go or if you have a link to it' that would be great.
