Stool errors (precision alignment/smart snap)

alignment gHello. I write here because I have a serious problem with lua scripts, precisely Stools.
my garrys mod was bought from steam 2 weeks ago.
So, i have problems with many tools including the weight stool from the workshop but more or less I’ve been able to fix them: they work but still trow some errors, like the name #tool. name…

But the real problem is precision alignment, that locks up the graphic engine refresh.
I usually play on a server where all works fine, but when douring the week I’m at the university steam is blo ked so I can just play on SP where nothing works fine.

Do I have the wrong svn links (grabbed on this site) or should I set up a dedicated hl2 server?

any help is appreciated
