I'm having this error with the game "How to train your dragon". The compatibility list says it works, I get this error message. I tried with Hermes v4b + 3.50 spoof and a few different managers (OM, Gaia, Rogero 7.8).
I know some of the problems with this are when you try to launch the game from the Backup manager directly i.e. you just press start. Also if you are trying to launch them without a disc in the drive and launch it from the /app_home/
So Try it with pressing X in your BM when it takes you back to the XMB and start the game from the normal place the on the XMB that has the Blue disc like its mounted as a normal game.
Actually, this is what I'm doing. I press X in the backup manager and then go back to the XMB to launch the game normally.
I forgot to mention I'm using the PS3JailBreak dongle and the 3.41 firmware. I also tried some of the different options with the Rogero manager, including the direct boot and the patch option, but still nothing. If I use the patch option, I get a black screen and then nothing.
