Alright, so I suddenly got the urge to play diablo 2.. so i go to my desktop, get my d2 keys, and register them to my account blizzard account.. I downloade d2, and d2 lod.. I open up diablo 2 all excited and ready to play and i click battle.net and BAM!
"Unable to connec to battle.net"
This happens in my domain region USEast.. This makes no sense.. So I go to my desktop and try to play on battle.net and it works..
I hop back on my laptop and try a different region and i get the error message
"Battle.net is unable to properly identify your application version"
This also doesn't make sense, cuz i downloaded right off of my account on battle.net.
Has anyone experienced this same problem?
Please help me! I really want to play

Gusher ,

As I'm checking the account, I see it's logged in right now and playing in a game. so I'll assume you were able to get it going.

The "Battle.net is unable to properly identify your application version" error is normally resolved by running the game as an administrator (if using Win 7 or Vista).
