running two different cd keys on one modem

[Dani666]

I recently had to plug both of my computers up to one modem. Can I play Diablo on two different computers but on the same modem? When I try to log on while the other computer is online on Diablo II lod it says the cd key is being used by them but we have two different cd keys. Can anyone help?

You may have installed the same CD key on both systems. I would uninstall both games completely then start over just to make sure.

The modem has nothing to do with the CD key, it is just a portal to the internets.
