multiplayer not working x wing ballance of power

[jigglywigglyxxx]

so we both have balance of power
2.0 installed

i have tcp ip selected, this is on lan

windows 7 btw

i enter the host's ip address correctly 192.168.1.234

and host is already hosting.
But it just sits there on connecting

same thing happens if I host

why is this? Same lan and everything, 192.168.1.0/24

Is windows 7 the problem? Help please, thx.
