Yo, my Hammer editor executable all of a sudden stopped working. Before this happened, I was looking through the area where you can change the active FGD being used for a certain mod to map for. Well, I hit the edit button so i could manually make entities show up as models. I noticed that everytime I do that, switching back to Hammer with the fgd still open makes the Hammer windows all white. So i continued to edit the FGD. When i was done and saved the changes, Hammer, instead of going back to normal, stayed white and unresponsive. I Terminated the executable through windows task manager. I tried to start it up again, but nothing happens. The task manager shows that hammer.exe is running and using around 50% cpu usage. So I redownloaded the executable from the Valve ERC site, and overwrote the existing Hammer executable in the directory. Still won't start up.
Any help would be greatly appreciated. Thanks
