To begin, it says it needs a newer operating system to run. I have Vista 64-bit Service Pack 2. I click okay, then "already activated." It then brings up the installation screen where the bar just stays at 0%. I see that many people are having their installation get stuck at around the half-way mark. I wish I could get that far! IDK what to do and Blizzard is really pissing me off. I guess once they get your money its all good for them. Any ideas?
