monster hunter freedom unite

so i downloaded the game save to my desktop. extracted it. copied game save to savedata. went to xmb to saved data utility and saw that if copied it right. started the game and when it tries to load the game save it says the file is corrupt. thought i had the wrong region game save went back here got the right one. same name as the game save i have now and yes i took my file off and put the new one and overwrote my original file. it still says corrupt file. am i missing a step somewhere? thanks for the help! im running cfw 4.01, think maybe i should upgrade to 5.50?

I guess the save is corrupted then?

upgraded to 5.00 m33v6 and the downloaded save game worked fine. so im guessing that any saved game is only compatible if the user has the same CFW as the person that uploaded the file.

Hm yea I guess that's it, thanks for the heads up.
