Forgive me if this has been posted already :blushing: When I start SDK and Hammer for TF2, I get about 30-90 seconds of activity, then it locks up. I have to open the task manager to close Hammer from that point. This has been going on for several months and my quest for answers has brought me here. Anyone else having this issue, or know how to fix it? I've defragged, uninstalled/reinstalled SDK, verified files, deleted content, started from scratch, opened existing works. When I start Hammer, I get this in the messages window: I have no idea how to correct those errors. I haz teh stumped.
