What the cause is and how to fix it
This error message is encountered whenever you try to join a server that is running a different version of the game then you have installed.
1. Often this happens when a new version of NS is released and you haven't upgraded yet. Check our front page news
and our game downloads page
to make sure you didn't miss an update.
2. You can see what version of the game you're running by launching Steam and seeing what Natural Selection is called in the list (ie, "Natural Selection (beta 5)"). Make sure you are only trying to join servers that are running this version. This is often a problem when we're doing internal testing of a new version that hasn't been released yet and those servers show up in your browser.
3. If you're still having problems, you may want to try re-installing Natural Selection. If you do this, you may want to back up your config.cfg
first, if you've added your own customized scripts.
To re-install NS, open up Windows Explorer and find the directory you have Steam installed to (by default it's C:\Program Files\Steam
). Then navigate into the "SteamApps
" directory, then into your Steam e-mail address directory (your Steam "user name"), then into "Half-life
", then into the "ns
" directory. You may see an "nsp
" directory instead of or along with your NS directory. You'll want to delete both of these directories (keep in mind you'll lose any screenshots or custom maps you've downloaded as well, so move these to your Windows desktop or other place for safe-keeping first if you desire).
After deleting those folders, you can re-install the current version of NS
. After doing this, you should no longer have this error.
Good luck, and let us know how you do!
