Bf3 premium please help

First during set up you'll log in with your existing Origin account and you'll redeem the Premium code which will make your account premium and allow you to download the maps manually for free.  Here are the instructions for all three platforms.

FOR Xbox360:

After you purchase Premium and redeem both the online pass and the Premium code and your Premium file downloads to your console make sure that you restart BF3 so the game initializes with the Premium file present.  When you get to the main title screen you will receive a pop up stating you are now premium and you will have a Premium background.  Next you will have to download the DLC expansions covered by Premium (the file just gives you access to download them but doesn't download them for you) via the Premium tab of the BF3 in game store (not via the Xbox Live Marketplace or it will charge you money again)then close BF3.  After all 5 expansions completely download (this could take a while since each expansion is about 2 GB) start BF3.  At the main menu you will receive a series of pop ups stating that you now have each expansion.  Now from the main menu go to multiplayer, open server browser and then open the server browser filter by clicking R3 and check all new maps and game modes or you won't find any games on the new expansions. 

 For PS3:

After you redeem your Premium code make sure that you restart BF3 and upon restarting at the main title screen you will receive a pop up stating you are now premium and you will have a Premium background.  From the main title screen go to the BF3 in game store and download the DLC expansions covered by Premium via the Premium tab of the BF3 in game store then close and restart BF3.  After the expansions download go to the games portion of the XMB and click on each expansion's bubble to install the game.  After each expansion has been fully downloaded and installed restart BF3.  At this point you will receive a series of pop ups stating that you now have each expansion.  Now from the main menu go to multiplayer, open server browser and then open the server browser filter by clicking R3 and check all new maps and game modes or you won't find any games on the new expansions. 

For PC: 

Start BF3 in Origin you will be prompted to download your expansions.  If this doesn't happen right click the BF3 icon in your games library and select "show game details" then on each expansion right click and select "download".  After all selected expansions download you can play BF3 on the expansion packs.  Then go to Battlelog, multiplayer, server browser and at the top of the page add the new expansion maps and game modes to your server browser filter settings to find games on the new maps.
