Kliener? Causing lagg and crash's INVISBLE!

I need help.
I finally found out what is lagging me extremely bad, I have hl2 hl2 ep 2 ( and more like all of the source games you could possibly think of )
Well I found out that, Kliener is invisible to me, I cannot see his model, I use to see him untill i reinstalled gmod
I also know its kliener because my console is being spammed like 500 msgs a second with this, Which is causing the lagg

MY QUESTION IS HOW CAN I FIX THIS? ANY KLIENER MODEL REPLACEMENTS? OR THE ORIGINAL?

You could try extracting the Kleiner.mdl from the Hl2.gcf, then putting into garrysmod/garrysmod/models

Do you have any weird replacement mods? I remember having this when I tried to replace two completely different models.

Problem is still not solved =/

Did you have any replacements? If nothing works, first, try to rename your addons folder. If it works, there are some addons that are screwing Kleiner.
If it doesn’t work, rename your garrysmod folder. If this doesn’t work, it’s a serious problem.

No i did not have any replacements, I just now added a replacement to see if it would work ( atleast I think its a replacement, its either that or just a spawn replacement but not the real model )
And it did not work
I renamed the addons, it did not work
Kliener is invisible and I get spammed with this msg in console still

What happened when you renamed the garrysmod folder?

I renamed my gmod folder to my liking and it fixed the lagg problem and kliener problem
I now get 100 fps again
1 problem, What was the problem? And how may I fix it because Now My addons and old settings arent working

Edit: Nevermind, Its fixed now, Im going to install some of my old things and if it happens again I know what too do =] Thanks

If you don’t really need anything else than your addons, name the folder back to garrysmod, and delete everything except for the folders you use, in this case addons and settings.
