SOLUTION FOR LAZY PEOPLE...
The solution's simple, if someone would actually post up their VP it's not hard to move their VP on to your account. How to do this, you'd need a seperate PS3 account/USER, (and PSN in some cases.) For instances: Mine -
Main one with my own VP: DSE (ALL MY GAME-DATA'S ON THIS, AND MY PSN IS CONNECTED TO THIS.)
(OLD USER)
Alternate one: Gumdrops (NO GAME-DATA HERE.)
(NEW USER)
From there you take your USB it sounds harder than it is lazy people! You then put it in to your computer... :O Download the data for the VP then you put it back in to your PS3! (How incredible!) You don't upload the USB game-data to your regular account you upload it to your (fake/alternate,) one then from there you can do something truly remarkable! YOU CAN COPY DATA FROM ONE PS3 USER TO ANOTHER :O!!!!!
(Note: Most of what I'd said is sarcasm since everyone's asking for the solution, yet the solution's pretty obvious but people are too lazy to level their own VP's and create new PS3 User(s) to use another persons VP.)
But yes that's the solution!

Need the help from somebody who has experience hacking encrypted saves.
Fifa 11 isn't hard to work around to be honest. It's not "encrypted," in the sense it seems you think it is. (However, it is partially encrypted.) For anyone that's opened it on Hex-editor, would have noticed the "language," down the right. It's not encrypted or anything like that, I'd personally suggest if you're trying to mod it. (I haven't had a lot of time reading, so I don't know.) Is to open it with C++ or C I'm pretty sure it's wrote in one of them. (That hex-edited part anyway.) I've also noticed they've used python as a glue to the Playstation 3! Huzzah!
