I already have the spring engine and I did what it asked me to, to put it in my spring/mods folder, and i see the files and everything, but when i launch spring for signleplayer, I cant launch it. is it multiplayer only, or map specific? should i just get the full install?

Which version are you trying to use?

Version 1.07

Problem solved, I deleted my old spring, got the full install, updated it, yada yada works now
