Hi ranh25,

This error is stating that you cannnot run this software where NAT is enabled (Network Addreess Translation) how are you connected to the internet is it through a router. if so is the router using NAT to connect you to the internet. if thats so you need to turn off nat. you need to have some proxy. you can also try this on your local area connection remove the defult gateway and try.

Hope this helps

Cheers !!

when i had xp it workt ok but now nothing.
i cant connect it & i dont know what 2 do with the second peagref of the defolt gateway
