Cannot load map

[Supertanker]

Every time I try to play a map not in a .pk3 file, it starts to load and then says "RE_Load_Map: Cannot find maps/test1.bsp"

And I looked, and it is there. What gives?

pull down the console with ~ and first enter "/sv_pure 0" after that you can load non .pk3ed .bsps with "/devmap mapname"

Okay, that worked. Thanks!
