Counter-Strike Crash Fix New Version
Today I am releasing a new version of my client sideCS Script
patch (http://www.nextwish.org/nwcscrashfix.shtml ) which temporally

I am also releasing version 10.1 of my (in)famousWell if that doesn't get your, well, damn, I can't finish the sentence.
counter-strike script (http://www.nextwish.org/nwcs.shtml), which to this day is still one of the easiest scripts to get up and running. All you need to do is extract it to your Counter-Strike directory, load up Counter-Strike and goto the controls menu and setup your keys and your done!
