I need to use Hammer in the 2009 engine so I can use "Propper" for compiling some brush models for my map. Since they fixed Hammer, I run it by opening the bat file in the steamapps\common\Team Fortress 2\bin directory. There isnt a source2009 folder like this steamapps\staticx2601\sourcesdk\bin\source2009\bin and running the bat from there only gives me a FileSystemMount Error 217, like what regular hammer was giving before they fixed it. Does anyone know how I would run it in 2009? That version was buggy after one of the updates and made a mess of the grid, but I was still able to use propper without problems.
