A while ago I got a couple of DLC Map Packs for Black Ops 1. I recenntly by given a new PS3 because the old has trouble spinning a disk. I had someone help me do a save data transfer but it didn't carry over the DLCs. How to I redownload them to the new PS3 without deactivating my previous PS3's psn account for myself?
All you have to do is activate your new ps3 with your psn account. You can have up to 2 active ps3's per account, for cases like this is the thought behind it. Once you activate the ps3 with the account you can redownload your dlc's through the playstation store with no problem at all. So as long as you didn't give a friend's ps3 access to your account you will be AOK. If you did then you can force deactivate all ps3's or a selected one on your account through the SONY site or ask your friend to deactivate your account on their ps3. I did this once they restricted the number of active ps3's to 2.
