Multiple copy in 1.10?

Is there a way to run multiple copies of d2 now?
I have 2 sets of keys and I've tried the onlyer cdkey.mpq thing together with the loader and the d2sfx.mpq file but the diablo crashes when the main menu opens (loader's fault) and I can't open more than 1 instance.
I've tried to run two copies using 2 windows-users but it didn't work
Thnx

Make sure you set up Onlyer's properly. it can be quite confusing your first time around, but just go over some of the older threads about this and make sure you didn't do anything wrong.

I personally have not tried it yet, and I don't know if it is still possible, but that is just something I would check out first. use the search button to find related topics.

Thx, I found that there's a new onlyer loader working for 1.10.

that's nice, can you tell me where the new onlyer for 1.10 is??
