Same version of d2nt which is?
3.0
or 3.1
(if you are unsure, simple mouse over D2NT Manager.exe and see if its 3.0.0.0 or 3.0.0.1)
I do believe that in 3.0 this is a problem
but are both bots using the same installation of Diablo2 just different cdkeys OR
both using different different installs with multiple cdkeys mpqs??
