Both Teams are Full error

You need to have both info_player_counterterrorist and info_player_terrorist entities in the map, or the game will not be set up correctly. See Making Counter-Strike: Source Maps for information on the necessary entities. Also check your console if it reports that your spawn points are invalid try moving them a little bit like 2 units up or something. The problem is usually that your spawn point entities are intersecting another surface in the map (usually the ground), and thus the spawn point is invalid.
