Madden 2004 small bug

The game boots in properly (at least the demo version does, although i had to 
install the game via windows and import the reg keys) but the mouse cursor is 
invisible (or stays in the centre of the screen, while the game actually 
tracks it properly) and makes it virtually impossible to navigate the menus... 
not sure if it will go in game if this bug is fixed, but the main menu has 
graphics with random players doing moves, so its probably not far off from 
working.. this bug also exists in maadden 2003, although i did manage to get 
in game with some tedious mouse movement and the game worked although the 
sound was slightly scratchy.. anyone know whats causing this?
