Weird Problem ...

First of all I am really sorry if this question has been asked already, but I tried to find it via Search but it didn´t work.

I have my Ps3 slim on 3.55-kmeaw and MultiMan. When I try to launch a game from the internal it doesn´t work telling me : "This title cannot be loaded from internal hdd, transfer to external usb hdd or change title options"

I tried everything but it didn´t work. So I copied the game to my external drive.
Then every game started working :D But 1. question : How can I make them work on the internal :) (Maybe : How to "Change title options).

Now for GT5 when I put it on the external MultiMan says that it can´t be launched on an external because of the Split files :wow: And the best thing : "Put it back on the internal" :p :lol: And the other Hint is to use the Hermes Option (no idea what it is).

Please Help me :D
