NS starts up fine, and i can look at all the servers and play one or two of them, but most maps, when i try to join them get to the validating server info bit and then tell me that my my Map [maps/<mapname>.bsp] differs from the servers. How do i resolve that?

thanks

You probably got a bad installer. Uninstall NS and redownload the installer, then reinstall NS.

When I try to join any server a pop-up comes up saying that my dll differs from the server. How can I resolve this prob, any help would be much appreciated.

Thanks
