I have a map that I've been working on for some time, but stopped working on it back shortly after MTP came out due to some IRL issues. Since then I've not opened the file till today, when I discovered that it no long opens. Its gets to about 33% in the postload processing, then Hammer just crashes and closes. I even tried this with Windows Task Manager open on my second monitor, it just disappears and I have no idea why. Now I know there have been 2 minor Source SDK updates fairly recently, could they have effected something? Just to be sure I've checked the SDK itself (verified the cache integrity and all that, and I can open other maps, its just this one map that won't open. Any ideas or suggestions?
