Need some quick help, I'm making the map for Source SDK2013, I got Hammer++, but when I try to run it, it either boots up SDK with nothing, or I get some errors like Player start leaked, and Loadportals: couldn't read map.prt? I can't seem to find any specific tutorials on Hammer++ and source SDK2013, or any easy to understand way to fix these issues, anything pointing me in the right direction would be really appreciated! I'm really new to any map stuff in Source, so I'm a bit of a fish out of water, specially since there doesn't seem to be any recent tutorials for this type of stuff, I just wanna try to make a map for this contest, or just to learn how this works
