Gotta admit tho, it's very weird that these kind of issues still exist when game is at ver. 1.30 already. Kind of sad.. Anyways, hoping this will get solved soon!
yeah - but on the bright side, I'm sure they'll sort you out quickly.
I think the problem is that the 2 characters were provided as DLC and are not directly unlocked in any version of the game automatically. It's quite possible that SD did something to change the process that added the DLC automatically to accounts that buy DG so that now it doesn't work for everyone. I'm pretty sure there is a registry setting you can change to get access to the dgs in single player mode (on the forums somewhere...), but I don't think that changes enables them for online play. I might be wrong, though.
Anyway - hope you get sorted out without much delay!
