Still need more details on what exactly you did in the game immediately before getting this problem, more details on what exactly you are seeing, what type of computer you are running the game on, what version of the game, what, if anything you've done in the OOTP5 folders (deleted a league folder or file?) recently?
Without these details we really do not know enough about what is going on to help you. The more details you can provide the easier it is to help you, and the more likely you are to get help quickly.
