@slug2631, when that happens it normally means you're missing textures, most likely HL2, CC:S or something else, if it is something else i cant help you only the map maker can by linking the textures but if its half life 2 or CC:S then you can either buy the games or download the textures from the workshop and hope it works

when i load into the map it says error every were and the map is purple and i dont know why
