NSOWNS555

<div class="IPBDescription">NS Crashes when i connect to server</div> When i connect to a server , right before it connects it says "disconnected, your DLLS do not match the servers"

How do i fix this? It was working fine yesterday...I LOVE NS and i need to play it!!!! someone please help!!!

Also , all of a sudden, NONE of my half life games run in full screen mode unless i put them in 1200 x 1600 resolution...This makes the graphics very pretty, but the framerate suffers....All my half life games, counter-strike, NS, and the specialists, all run in window mode until i put them in 1200 x 1600, and this didnt happen ever before... Any assistance is greatly appreciated

This will install beta 5 no matter what you have done before, so start at the begining!
1) Install Steam (Get the one with the HL cash if you can), if you have already installed Steam you may skip this step
2) Play HL Via Steam (just load up the training mission and then quit)
3) Search Your Hard Drive for NS and NSP
4) Deleate ALL Folders with these names.
4a) If you have a previously working install of an earlier version that you wish to keep: You can rename all NS folders to NSBUP and leave the NSP Folders alone.
4b) If you have a previous install of NS, and wish to keep your configs, cimply copy your .cfg filles (normaly just config.cfg and userconfig.cfg, to your desktop)
5) Close Steam.
6) Run the Beta 5 installer (ns_install_v3_b5.exe)
6a) Point the installer at Steam\SteamApps\Your@email\Half-Life
6b) If you backedup your config files, now is the time to move them to your NS folder.
7) Launch Steam
8) Change your filters so that the point at <b>Natural Selection(Beta 5)</b> Instead of <b>Natural Selection (Beta)</b>
9) Connect and play.
10) If you get any errors (map.bsp, client.dll, or <b>ANYTHING</b>:
a) Search your HDD for NS, there should only be a dir called NS in your Steam\SteamApps\Your@email\Half-Life\NS, unless you backed up a previous install.
b) If it is ANYWHERE elese, try moving it to the correct place, or simply deleate it and start again.


If you still get map.bsp errors, or client.dllrors, start from step 3 again.
If you are POSITIVE that you hvae folowed the directions correctly, then redownload  ns_install_v3_b5.exe from another location.<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->
