Toybox not working??

Hello, after the new update in garrys mod you have “ToyBox” in single player.
Its looks really awesome, but I cannot spawn anything from it?! And sometimes I get an “unknown error” that he cannot connect to the server or something else.

Can anybody help me?

Your avatar and profile link make me wonder…

Well I’ve got the same problem with toybox. since it has its own tab I’m unable to spawn anything from it.
