Suppose I have two PS3s, both with different accounts at different places. I have the CoD4 maps downloaded on one but I can't redeem the promotion code again, and I don't want to buy the maps again for £6.99. Can I download the maps again on the other PS3 by signing in the account that has the maps? I think each one can be downloaded 5 times, would I need to log out of the original PS3 first? Is it the same for any games I bought from the PSN store?
