For my surprise, this thing is still up and big thumbs;) But when i installed game (original disks from shelf) many warnings were there. I did not care, thought this game is old, they are supposed to be there. But what then annoyed me, I could log on my old account, could see all my old characters, but after selecting one and trying to get in, "CD key error". This I can understand, seen this before on many forums. But interesting, i can log in in any given new "account", per se any name and pw, and i can get into game, as long as not the one i had here.. So maybe worth looking into. Not for me, but if this affects others too, maybe some old players have problems with this too and don't bother to work for it..
this is a security feature of the module, you need to request from the development team that your new cdkey to be associated with your old account, then you can access your old account, provide your old login account name and they can take care of you.
