Query: Finnicky installation; no support

After ensuring that my system exceeds not only the "minimum," but also the "recommended" requirements, I installed it. Got a "Client Error" message. Activision's website acknowledges the problem and recommends turning off all other processes (including firewall & virus protection!). Did that. Still got the error message, so I contacted the tech support e-mail account. That was 10 days ago, but I still haven't received a reply. Phone support isn't offered during evenings or weekends, either.Sluggish and choppy graphics may be bothersome, but software that just doesn't work is a real pain.
