I need help with installing Portal maps. I tries to install the map "Portal Playground v1". Google it if you're unfamilar with this map. The .zip contained 3 files, a .bsp, a .bns, and a .tga. Upon opening the .tga, QuickTime poped up showing that the .tga must have been the icon in the bonus map section. I put everything in the C:Program Files/Steam/bobbysq(friend me!)/portal/portal/maps directory and it half worked. The map shows up, but can't be opened unless through the console. Is this my problem, or is it the mapper's?
