It was me anyway the basic problem by now is always the same,i'm able to play games old and new ones just by putting the dongle before turning on the ps3 but i'm impossible to update it cause when i try to run update 2.5 it goes on the red light saying it can't find the dongle tand then it can freeze or simply reboot my ps3 system and go green again..
EDIT
Ok i checked online and all i needed to do it was just watching on system information and it came up the dongle is already updated with the last firmware 2.51 so i assume that's why it came up the error,i'm gonna test other games in the next few days anyway thank you lightake for assistance and fast delivery.
Update
I tried 4 titles by now and they work great ^^
