Help downloading mass effect 3 through origin!!!

hello, i used to play mass effect 3 for ps3 but recently got a new pc so i decided to buy it for pc. i bought it off of the mass effect 3 official website. i downloaded the game the first time yesterday, along with all of the dlc. when i open the game, the first error i get is: "the mass effect 3 server is unavailable at this time. please try again later." after i click OK, it begins to check for the DLC content, which i have installed. i then get the following error: 

                                                                                                                "Unable to authorize the listed DLC. 

                                                                                                                  Please log into the alliance network with the account used to purchase the DLC. 

                                                                                                                  ME3: Content Patch DLC Module 

                                                                                                                  Multiplayer expansion pack 4 

                                                                                                                  Mass effect 3: earth

                                                                                                                  Resurgence multiplayer expansion 

     The following downloadable content is corrupt and can not be used. Pleas re-download the downloadable content and try again"

I tried repairing all of the dlc content and the game and that did not work.

I also uninstalled the game and re-installed it over night, and i still get these same errors. I looked around on google and cannot find an answer to my problem. Any ideas or help is greatly appreciated.
