Can´t use tools on world. HELP!

I can´t use any kind of tool to world.but,it seems that it works fine on props,but not the world.So,the proplem is when i face to world with thruster tool ect. (ground .ect) it won´t fire(create the thruster) to world.I can spawn entities and props.If anyone know how to solve this please,tell me if i can get rid of that nasty proplem.

reinstall gmod? :smiley:

Do you have any kinds of admin mods or anything? Is this a server or is it singleplayer? Be more precise , the more details , the more help…

yes,i have ulx and ulib. but they work good never have any proplems with´em.Yes and i am playing in singleplayer (mostly),but i haven´t tried multiplayer,since this proplem.I am not minding reinstall gmod cause i downloaded hours of addons.Tried to delete the crappy ones but no.Currently my addons are from phx3 to Kermites sweps.(about 14).I am not going crazy with this proplem yet i am not into games.

Ok guys i fixed this!ANYONE WHO HAVE THIS PROPLEM,DELETE THE “GAMEMODES” - FOLDER THAT SHOULD HELP OR “SANDBOX”.
