Clicking OK in "Run Map..." does nothing (L4D2)

[SombreErmine]

I'm trying to get back into Source mapping; so I downloaded the L4D2 Authoring Tools and ran Hammer. I built a simple level and tried to run it, but nothing happened. Assuming I had missed something vital, I loaded up one of the tutorial levels that comes with it, but when I tried running it, nothing happened again. There is no compile log. There are no errors or warnings. The "Run Map..." window just simply closes and does nothing else. Here's a link to a screencap video to illustrate what I mean.

What I've tried to solve the issue, and nothing changes anything:

• Verifying the local game cache on both L4D2 and the L4D2 Authoring Tools
• Verifying the Build Programs paths
• Resetting the Game Configurations from inside Source SDK
• Running the L4D2 Hammer editor manually (not through the authoring tools) with Administrative rights
• Restarting my computer
• Uninstalling all Valve-related games and tools, deleting their leftover folders, and reinstalling L4D2 and L4D2 Authoring Tools (running L4D2 once before opening L4D2 Authoring Tools)
• Turning on "Wait for keypress when done compiling" does not keep the compiler log open because it never runs to begin with

I'm wondering if this has anything to do with the Steam Pipe updates screwing with my build or something. I've searched with several different keywords looking for anyone experiencing the same issue, and the closest related issue happened back in 2010. Their solution ultimately was to use Nem's tools instead. I don't want to have to resort to figuring out how to do that for L4D2 if possible. That's why I figured I'd ask and see if there was some known solution to this.

I really have no clue how to solve this, but I really want to prototype an idea I've been contemplating for some time now. Any help would be greatly appreciated. Thanks!

Does the map work the normal way, ie launching l4d2 with -console enabled and typing map mapname ?

[SombreErmine]

Unfortunately, it does not even get to the compiling stage thus there's no map to load in the game. I looked in the maps folder assigned at the bottom of the "Build Programs" tab of the Hammer options.

Post the compile log.

[SombreErmine]

As I said in my original post, there is no compile log. If you look at the video I posted, you'll see what I mean. If there is some magical location that it creates a compile log file that I am not aware of, I would love to see it myself.

Hit the "Wait for keypress when done compiling"

[SombreErmine]

That unfortunately does not do anything. The compiler does not even start. I appreciate the assistance though!

Go into options and make sure the compiler paths are set correctly. This is what my working paths look like.

They're the same. :/
