Didn't get very far last night, but the problem has now been centred around the Player Unit in the backbox. It is all seized up with hard grease and will have to firstly pull it apart and clean it so that everything runs smoothly again. Have been reading that if this isn't working freely, the game won't operate.
I also had another hit of the ball and the GI lighting died. Something more to fix on the game now.
Cheers!
Adam.
