Anybody know why the latest diablo 2 patch doesn't allow me to run the game without a cd? - diablo 2 patch bnclient.dll

I installed the latest patch, which promised that Diablo 2 without a CD is being run, and do not work for me, why, I installed all the best and I installed the full version with the kit has d expansion.

Does anyone know crack a that actually work or how to get the patch to run.
