So ive been struggling with this for the last couple of days but i copied over an old backup from an old ps3 kingdoms hearts 1.5 over to my fat silver ps3 over ftp. but now when i go to webman and try to mount the iso file to play it it first shows the icon for when its in the process of doing so and then it says loaded and right after it says error with the game name and serial number but no actual error codes. my fat ps3 is an evilnat CEX CFW 4.91. ive also updated webman on the ps3 itself with the update option please help a noob out thanks
