i think ur having the same problem as i am. i can play online ftb3 with the iso i have cause i put in the new tactics.prx but when i try to play off the game i have the same error.i dont even need to update or pathc cause it says im at 9.90. im running 5.50 gen-D3. why would it tell me i need to pathc in order to play? i can still play using the iso but i would like to use the disc i bought instead.
