Free DLC's download not working

Hey guys/girls,

Recently just purchased Mass Effect 3 with a bunch of buddies in hopes of playing the multiplayer co-op missions or someother. 

But I have been unable to download any of the DLC's that is either required by the game or required to play with them. 

The majority of us bought the game at the same time, but it appears that I'm the only one that can not install the DLC's.

I've tried pretty much anything any other fourm post suggests; verifying, repairing, uninstalling and reinstalling the game. Uninstalling and reinstalling Origin, Checking to see if Origin and Mass Effect aren't block by firewalls or anti viruses. Also removed the DLC folder from the Game directory and attempting download, also tried downloading the DLC's from; the Bioware website, from the in-game "Downloadable Content" option. 

Any help with this issue would be greatly appreciated, it's not a great feeling being left out when all my buddies are having fun. =(

Thanks.
