Need help with ISboxer

Hey guys, I recently tried to test the ISBoxer 40 that the gteam10x uploaded with their auth_srv and stuff like that.

The help I need is that I'm a diablo 3 player and when I used ISboxer 41 I was able to log to 2 acc and play well, but now that I have this one I open the first acc normally but the second acc opens the same acc over and over again, can someone help me with that? :/

Hopefully someone will be able to help me :D

Kind Regards :)

EDIT: I know this is probably a WoW focused website, but I think it's not a problem since I'm asking Multibox stuff and if u are able to answer it's really nice! :D
