Standart STools has disappeared

Hello.
I have big problem when moving gameserver on dedicated server.
Standart STools was disappeared, and gmod_camera doesn’t work.
Instead ‘Camera’ on 6 slot i see ‘PRINT NAME’ on 1 slot.
In console i see this error:
[lua]Error creating ‘gmod_camera’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘pocket’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘weapon_keypadchecker’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
Error creating ‘gmod_hands’ (Make sure the file is AddCSLuaFile’d and there aren’t any errors!)
[/lua]
Before this error I see:

Please, help me to fix that.
(If you need more info - tell in new message)

Thanks,
Pizhik.

Verify your installation.

bump

Still need help

Right click garrysmod in your game library, properties, verify integrity of cache file.

Nope.
This is not a local gameserver.

Validate files on your server then. Or just reinstall it of you don’t know how.

This happened to me when I installed a new addon, and I solved it by removing it again(tried different addons).
