Cannot connect to new CW server

Friend just set up a CW server, but I can't join it. I get the error "Something is creating scripting errors" in the top left and I get kicked instantly. Around 8 other people have joined with no issues.

Also, I've already cleaned GMoD and reinstalled, everything updated, etc.

Here's the console log:

Did he authenticate his game mode? Does he have his Serial Key? That's what fixed it for me.

 

Everything's authed and his serial key is inputted. Everyone else can join but me. I'm guessing it's something clientside.

 

Did you DL the gamemode through the Gmod 13 server list? The arrow at the right side of the gamemode?

 

If that's blue then someones been fucking about with a file they shouldn't have. Do a fresh re-install and try again.

 

No, I remember the text being yellow on output.

EDIT: I've tried defragging, reinstalling GMod, joining from a single player game, etc. I really have no idea what to do.
Also, I can't join any other CWHL2RP server either. I all get the same error, so it has to be on my end.

 

What?

 

Fucking quotes within quotes. I said (and it is in there if you look ) Perhaps it's the OS you are running? Shot in the dark.

 

Eh, Win7. Does CW have problems running on it?

 

No but there have been problems with Macs in the past.

 

I fixed the problem by setting sv_kickerrornum 0

 

That works, but I'll only be able to connect to that server unless another server has that option changed as well.
