hl2-garys mod. Quick question.

Hey guys a couple quick questions regarding garys mod for hl2.


First of all.
When I start the mod/game and load up a single player game there are no bots e.t.c. say I load the map "graveyard" theres no bots e.t.c. and I go to the edit menue for the mod and everythings like turned off...

So how do I get some bots added to the single player game?




Also question 2.
How do I unistall garys mod if I don't want it anymore?
Its sorta a big mod file-I dunno just wondering.
(I can't find a unistall file)


Thanks
