I experienced this too.
To be honest, i hope they drop the DLC lock already. Is buggy, is hard to buy and since they slaughtered Eden Games i don't feel like giving money to Atari.
Seriously, as a press member i was there when the hype engine was at full force, i played at least three builds and wrote 2 articles + a 30 min. review in our podcast, but then the game came out, it recieved so-so scores (i LOVED the game so scored it highly) and Atari just abandoned it, i also remember the mess the game were before that, and never believed (and still don't believe) it was Eden Games fault. If Atari had any intention to support the game since its launch, we wouldn't have seen that HORRIBLE DLC management, the debacle that was nearly every update and we wouln't have been almost alone in the forums. Heck, i even applied to be a Community Manager for the game.
So, if this bug becomes more than that or is proof that Atari is about to free the DLC i'll be happy, i'm not supporting the game anymore in the sense that i must keep legal and i must keep the game files untouched. I'm not stealing anything, but i'm modding the heck out of it and not using Uplauncher anymore. I promoted the game, i bought the game even when they gave me PC and 360 versions for free, i bought all the DLC i could before buying Atari Points became a chore that required a Paypal Account that forces me to wait 1 week before i can use my credit and i used their support ticket system before they stopped answering.
Eden Games earned my money, but they don't exist anymore, so i hope this becomes more than a bug.
