Please see "Quick Start" or readme or supplied user manual or online help.
In general : you have to setup server ip address and client number in local client settings.

still not working im using windows xp sp2 as a server and windows xp in client but still they dont see or connect each other any inputs here sir Oleg

Are you using server and client from one distributive ? Please tell their versions (build numbers).
For testing you can setup one client on server computer.
Also network connection may be prohibited by yor firewall, turn it off if present, temporary.

still not working or not connected client build is ver. 4.0 build 18574 platinum and the server is ver 4.0 build 31209 platinum. the server and the client these are the one that you gave to me is there any updates on this

Ok, we send you 4.1, may be your distributive was assembled improperly. Please write to clubcontrol (at) vaosoft.com country, city and cafe name.
