OK, if it is like that, don' t worry.

Just go on copying the working one to mod a copy of it as you like (GWX, WAC, whatever).
At the end, there is no need of the original installation, DO NOT deinstall that one, but delete the folders. All the Windows registry information are kept that way.

Unfortunately I have got any original copy today .Few days ago I deleted the last sh3/NYGM3.0(it worked well).
Anytime I can download and play a crack sh3 (l tryed)but i prefer the original for many reasons.
I will download the latest ones Videodrivers, and tell you if they work.
Thank you.
