Trouble editing

I've edited the pack and i'm having some problems. I edit it, save it with winhex or hexworkshop doesn't matter, when i run 2moons, not using bypass or any other thing and it doesn't crash, say invalid client neither does the hack work.

I'm using Vista, don't know if that is the problem.

Has it happened to anyone?

ah what pack did you edit and what did you edit it to do?

I just made it work, thanks for the help anyway.
