Problem actually running finished HL2 maps...

Im not sure if i have my game paths all set correctly in hammer. heres the thing. I created a simple room with a few boxes and a player entity for ct and T etc.. I clicked run up top in hammer and it compiled the map fully then it loaded CS source but then it just went to the opening screen of source. It never loaded a game. I went into create game and there was no map with the name i gave it. So i was wondering what i need to do to fix this.

Is the .bsp file in your cstrike\maps folder? Have you checked that already?

this happened to me before but I found the map, it's hl2dm, and ran it.
It goes 1 block loaded then it goes back the the main hl2dm screen. I
don't know what happened and how to fix it.
