hmmm...my box isn't due to arrive till Tuesday. I sure hope the cds work, 'cause I'll be a very unhappy camper if they don't! I was wondering though, did the Mac version of Shade come with a serial number, or was it in your confirmation? I see everyone mentioning they got a serial number with their email confirmations, but I didn't get one. I didn't know if the Mac one was any different, but I didn't want to write to customer service about it until I got the box in my hands.
