Re: How do I download premium maps for PS3?
I looked at your Battlelog Profile http://battlelog.battlefield.com/bf3/user/CorporalCricket/ and it shows that you have purchased Premium for your PS3 in addition to your PC platform. You will have to re-download your Premium file since it may have been deleted or corrupted during a title update in order to download your epxansion packs free of charge. Open the PSN store, go to our purchase\download history and scroll through your purchase\download history until you find your premium file, then click on it and re-download it and follow the instructions that I posted in the paragraph above.
Once you have re-downloaded your Premium file on the PSN 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.
