I've just recently purchased World of Warcraft for my computer. I have tried installing it numerous times. I have been back and forth with battlenet support and they basically told me it was either my computer or programming that was stopping the installation. I have changed my settings on my firewall, tried to install it from my disc and the website, deleted every program associated with WOW that downloads every time I try it, and I'm on the administrator account to my computer. I was wondering if anyone could help me out. I have tried Time Warner and A&TT WIFI and it doesn't make a difference. The error always occurs at 4% data/enUS/3expansion, on the blizzard installer. Any suggestioins???
