I can't figure out why my second computer gets this error. Luckily my main one works fine but my friends can't play NS with me when they're here because my extra computer always gives the same error. Your map differs from the servers. It doesn't matter what server I connect to, for almost every map it gives me this error. The only map I can think of that works offhand is co_faceoff. Anyway, it has the correct version of NS, i've reinstalled everything, I have even transfered the map from my good computer that works to the other one, and it still gives this error. Any idea of how to fix it?
