Help me please

Last night i was playing FIFA fine and everything. This morning when i tried to load it, the PS3 would recognise the disc and it would try and load, then it would go pitch black and do nothing, i have tried re inserting it but to no avail. Other Games like MW2 work but its only FIFA, please help me its my most favourite game in the whole world.|||No idea, but work on your grammar :)|||why are we in school * head
