BattleField Problem: Ive searched and tried all the so called "fixes"

If it still doesn't work, you can always use Clonecd to make an image of cd1 on your hard disk, and mount that using Daemon Tools. Both are free, easy to use and WORK. I use this method to play myself, so it really works. The ONLY disadvantage is that it takes up 700Mb more diskspace, but at least I can safely install any future patch without having to look for a crack for it.
