Cheat Engine

I read the "pointer tutorial" posted on CheatEngine board. (An excellent piece of work, and I truly appreciate that effort.)

I have some issues with the following games :
- "FIFA Soccer 09" (U.S. release)
- "Battlefield 2"

In "FIFA Soccer 09", I try to find the address of pointer. Whenever I try the option "find out what addresses this code writes to", the game crashes. It does not crash when I use the option "find out what addresses this code access", though.
There is a "database editor" available on internet, and I can edit almost everything within this game. That is not the issue. I want to find that pointer and that is what I am after. There are some trainers for this game, as well. None of them functions properly.

In "Battlefield 2", I have no chance to retrieve a mouse cursor. It sticks within that game, and there is no way to operate a mouse in desktop, at all.
I know that there are trainers for this game. However, none of them offers "invincibility". Additionally, "infinite ammo" applies to all players, and that means your enemy uses that as well. Yet, there is no trainer for updated version of this game.

Any suggestions ?
