My computer crashed. I saved all my files to an external harddrive, before I reinstalled my new operating system. My old one was 98 I now have Xp. I transfered SC2 back onto my computer,clicked on the sc2 icon, it said it wanted my e-lis. My son's computer has one, my computer has the other. I tried to enter the liscense it said error 11; both were in use. So I went ahead and uninstalled, which it uninstalled everything. So then I re-transfered from the external back to the computer again. Gave it my liscense, and it still says there are two in use. This is not the case! How can I get SC2 to work again on my computer? email: amosgraber or please reply here
