So I've been out of the mapping game for a while (November 2013 to be precise) and since then, TF2 has updated to the VPK filesystem... and it broke the SDK. I heard it was fixed, but I have no idea how to go about opening Hammer anymore with my old maps. When I open the SDK from the Tools menu and open a map in Hammer, I'm greeted with two lovely errors that then force-close Hammer: Now, the first one I have no idea how to fix, but the second is clearly because the new directories for the game have moved. I tried moving my old models+texture folders into the tf/custom/custom_stuff folder but it still cannot find them. Any suggestions?
