Lifesupport 2 problem!

Hey guys, I am trying to get life support 2 running on my dedicated server. (SVN isn’t an option)
So, I downloaded the version here:

Anyway, the LS tools don’t seem to work. Like the Marquee on the toolgun is correct, and I am able to select the tool from the list, but when I go to say spawn a generator it just won’t spawn. Like it looks like the tool works properly, except no matter how many times I shoot my tool gun I can’t get it to spawn any kind of LS system.
