Ps3 – download DLC onto more than one PlayStation 3

All your purchases and DLC are bound to your PSN account, not your console. If you deactivate your account on your old PS3 and activate it on your new one, you'll have access to exactly the same content (although you'll have to download it again unless you perform a backup/restore or direct transfer, which would also move any copy-protected saves you might have).

The exception to this is if you intend to keep your old console activated: You can have up to five PS3 bound to a single PSN-account, but (due to a policy change) any content purchased after November of last year will only be available on two consoles at any given time.

You may download any content you've ever activated (paid, promotional or free) as many times as you want, it will stay in your download list forever. (Source: I've had a PS3 since relase, and even though I've replaced my fat one with a slim, my download list still contains the very first DLC I ever bought)

I solved the problem. My friend SSFIV version is European. His psn user is american. When he downloaded the update kit, he did using the american ps store and the update kit is for the american version of SSFIV and even this package being installed, it does not changed his game (european version). Thinking about this, I said him to create an european psn account, access the european ps store and download the update kit. The european update kit worked as expected and now we are finally able to play.
