the exact same thing happened to me. A friend and i were xfering..then connection interrupted..and i couldn't join any other games..had to reboot diablo 2...yes..i did wait longer than 5 mins..but the game was gone..both my friend and i were booted..lost all my shit too..at one point i even e-mailed b.net demanding them to rollback my chr...unfortunately, they just sent a "violin-playing" letter

What is this!?! A center for ants!?
