Multi boxing 2 machines

Ok so ive read the forums and struggled through trying to set ISboxer/Inner Space up, i havent posted anythin up yet even though ive been reading these forums for a long time, but now ive come to a head, you see im trying to configure my 2 machines and ive followed the guides to the letter, the problem is in ISBoxer when i try to add my slave machine in the new computer from remote, it says *Could not communicate with LISA to retrieve data* (Lisa being the name of the machine i gave to the missus) ive opened the ports and even in the firewal settings made shure Inner Space and ISBoxer are in the exceptions, i used to use my 2 accounts ive had from vanilla with keybindings on my Belkcin n52te (hunter Warrior Combo) any help would be wellcomed

I've not done two or more machines with IS Boxer, but know it supports up to five.
The best place for support is the IRC, which will open right in your browser: http://www.lavishsoft.com/chat/isboxer.php

Can the machines see each other, for other applications?
If they can, will it IS Boxer run across the machines, if the firewall is disabled entirely?
