Full Story: So I was tired of my slow hard drive so I restored Windows 10 using the keep files options., the version of Steam I had on the old version was not in the X86 Program Files. Later, after setting steam and tf2 up, I wanted to import the map that I was working before so I went into windows.old and dragged all of my files into the current hammer location and it broke. This version of steam this time is X86. Problem/Short Story: I replaced x64 Hammer files with X86 Hammer files and it broke. Would be optimal if I kept everything else in the tf2 directory to be the same. (config,custom,maps,download) Solution: You go into where hammer files are stored in, open up gameconfig.txt and replace Program Files with Program Files (x86). Save and profit. EDIT: Finally fixed it.
