Well, it's way too late to reconcile with Mr. Chilly, but you can at least get back into the game if you go and create a Battle.net account now. Remember that, aside from being forced to do it now anyway, this also conveniently organizes all of your Blizzard game accounts into one place, lets you re-download any game for which you lost the CDs, and, uh, has a neat menu, I guess. Just go do it so you can play.
Your mother and I are very disappointed in you.
