Re: source sdk
I was having the same problem loading the Source SDK with Sin Episodes. This is what worked for me: When Hammer opens do not load a map or start a new one. Go to Tools, Options and then select the General Tab. Make sure that "Use independant window configurations" and "Load default window positions with maps" are checked. You will have to configure your windows as only one will be opened, but you can save your configuration and it should stick next time you open the map. That is what worked for me.
