Query: unusable program - save your money

I waited until now to review, hoping to hear back from Activision, but 3 emails and 2 1/2 weeks later we have heard nothing. Within a couple of minutes of beginning the program it crashes on both our XP computers, blue screen of death, have to reboot. Must be an error in the program.My child has been very disappointed, and I guess we're out $20 too.
