Unable to load Hammer

When I attempt to load a map in hammer via Source SDK I am confronted with an error, and then it crashes.


This is what comes up in the messages box, but there is no error until I attempt to open a map. When I click okay it closes


Not sure what the problem is, both CS:S and HL2 are updated to steampipe and I reinstalled Source SDK yesterday.

Navigate to your Team-Fortress 2/bin folder and scroll down till you see the hammer.exe. You can use that in the mean time.

If you want to use EP2 content, copy your EP2 folder from your Half-Life folder and paste it into your Team Fortress 2 folder.
