I'm going to help out everyone who could not open the map.
Hi guys, I'm just another TF2 player who wanted to try this map out.
Like most of you, I was not able to open the map until I tried something.
So if you follow all of these directions completely, you'll most likely get something like
"Pending: blah blah blah".
That's because you put in the code wrong.
1. it should be "map tr_walkway_rc2" without the quotation marks, not
"maps tr_walkway_rc2".
But here was the real problem that stopped you from loading your map.
If you look closely in your rar folder, you'll see another file named botmaxconfig.cfg.
For some reason, when I put that into my cfg file, that you can find in your tf folder, the game loaded after a minute of waiting.
So 2. Move your botmaxconfig.cfg into your cfg folder.
Again, I'll repeat the two steps.
Follow all instructions.
1. move your botmaxconfig.cfg into your cgf folder.
2. type in "map tr_walkway_rc2" without the quotation marks in your developer console.
tip: If you don't want to open up developer console after joining a server, just put "-console" in your launch properties before you start the game.
I hope that solves all of your problems. Enjoy the map. I'm about to go play it too.
