The task: make a trainer for the included Minesweeper game with Windows to stop the timer from advancing. I found the code address, and I made this program. However, it doesn't work 
.
Am I allowed to ask someone to look over my code and tell me what's wrong? In case I am (:-D):
Using Hutch's Masm32 8.2. The problem is that when I press the 'u' key, the program crashes. And SoftIce doesn't pop up, which is rather annoying. Keep in mind when you're reading this that I am really new at this, and this is my first attempt at a serious one of these type things. Don't make too much fun of me.
Thanks.

Thanks.
And if so, were her hands cold?
