Grey Screen Tic-Tac-Toe

[BR8N03epsilon]

Hello. I have been programming for almost a year, though recently I got Allegro 5 for game-making. I wrote a program using Allegro for Tic-Tac-Toe and I can't find what's wrong. At the risk of looking like a terrible debugger, I have been searching for about 2 months, though not constantly. I use Code::Blocks 10.05 and Windows Vista if those matter.

Here's what happens. I will hit compile, and it will load, another window will open (the game window), but it will turn grey and say:

Tic-Tac-Toe.exe has stopped working
A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available.

Unquote. If anyone has dealt with a similar problem, please help. I have taken out empty lines to save space, leaving 243 lines. Please excuse the size, as I am quite a novice at graphics.
