EDIT - I found it! :D It was D2-CdKey Now that was hard wasn't it... :(

I'm trying to remember a a program that I used at one point...

Basically what it did was make key files so that if you were using loader you could run the D2.exe with a different extension on it and it was a different key... I can't for the life of me remember it however...

Regards,

Glad you were able to find it; I always enjoy when people are able to figure things out for themselves. It saves people a lot of time having to flame them to "Google it!" and everything, heh. Guess if you got this solved...
