Ok, So recently I purchased 25$ for my PSN Wallet to buy Escalation for Black Ops and I had to do a File Restoration on my PS3 today now I have 7$ left and no Escalation Map when I was just playing on it 3 days ago. Like can Sony put 25$ back into my Wallet or what because thats kind of stupid.
Oh Really? I didn't know that.
Go to PlayStation Network / Account Management / Transaction Management / Download List. From there you can see a list of all of your purchases and re-download anything you want.
