ok i was taking a stab at making a first map and everything was going sweet until i clicked on the first.bat and i thin kit compiled fine because it made a first.bsp except counter strike didnt open. so i clicked on open cs and clicked on create a server and went to play my map. it sisnt open and this appeared in the console:

CModelLoader::Map_IsValid: 'first' is not a valid BSP file
map load failed: first not found or invalid

can someone tell me wats goin on? thanks

and i seem to play all these different variations of maps when i'm playing, can someone point me in the direction to downloading maps that i can modify like de_dust and stuff?
