I haven't played this game in awhile. I have Might and Magic Heroes 6 (bought it for $60 when it first came out). I tried to play this game recently, logged in with email and password, then it popped up a shades of darkness box asking for my cd product key. I don't have shades of darkness or any other expansions for this game. I tried putting in my CD key, but it says its already in use on another account, which makes no sense cause I only have one account...the one I just logged into. I can't get past this point. Steam support told me to delete all files in the steam folder except userdata, steam.exe. and steamapps. I did this, and restarted my computer, but I'm still having the same problem. Anyone know how to get past this?
