Hello,
i have a lil problem here at my ps3.
Before nearly every 3.55 user was offline for months/years from psn, i had some psn games on my ps3.

Some were bought, some were shared.
Since we can now go back on PSN/SEN, i know that i can download my old stuff.
But some shared games wont work anymore, like Dead Nation, which i rly wanna play again.

I cant login into the shared account to download it again, but the game is left on my ps3. Its full version, i guess the update from cfw 3.55 to 4.21 made changed something for the game, so that it doesnt work anymore.

Can i somehow resolve that problem?
I read about reactpsn, to resign a file or something ... but i never did this. And i dont wanna screw up my new rogero cfw ... i still wanna go online, i dont want to install somthing that i maybe dont understand and enable something stupid

So please gimme a hint how i can solve my problem!

Thanx!
