So I downloaded Sandbox 3 yesterday and I started fooling with it today. When I click on file>open>(map name) it won't load the map. I've tried about 5 maps, but none of them will load. It will close the window with all of the maps, but then it won't change. I can make a new map and fool with that, but I can't open a map from any of the levels. Above the console there's a message that says:
CShaderManBin::ParseBinFX_Technique_Pass_LoadShader: SHDataBuffer has been exceeded (buffer=9000, count=9250). Adjust buffer size to remove unnecessary allocs
Maybe that could have something to do with it. Thanks!
