Built .exe Won't Run

I’ve been able to build my game in the past, but since updating to 3.5, everytime I try to play the game I’ve built I get this error:

Failed to initialize Player
Could not preload global game manager #0

If somebody wouldn’t mind helping me fix this, could they at least tell me what it means? Perhaps there’s a .dll or something I’m missing? If anyone can lend a hand, it would be greatly appreciated.

Rebuild the game. Looks like one or two files are corrupted.

This happens with FTP because default mode is often ASCII instead of BINARY. But this can also occur when moving files between different file system (from Mac to PC for example).
