Re: Issues with DLC
@LTmighty Which DLC(s) did you buy? If you purchased and installed Trespasser, you should have 2 choices available for your ability upgrades, the main part of the DLC isn't available until after you've finished the main game. If I remember the other DLCs correctly some things you need to reach a certain point in the game to get/activate, some things are items which you collect from your rewards chest (I think some of these also require you to be at certain points in the game).
DLC content can sometimes take a bit to show up in game, as it needs to be verified by the servers first (just play the game while logged in to give it time to do that). I'm pretty sure installing DLC partway through the game shouldn't be an issue (only an issue if you uninstall it).
