Oh. I thought you meant you had fixed it by manually restoring the file from... I dunno, some website. There are a bunch of sites that host individual DLLs, for example, for people whose computers are mysteriously missing them.

Hate to say it but I'm pretty positive this is user error. You must be doing something wrong throughout the process of reinstalling BOTH the SDK and TF2.
At this point I'd say wipe steam and reinstall it from scratch.
Try keeping that monitor on while you open it? Hammer basically seems to like to pick a monitor at random on my setup when it comes to opening things.
Worth a shot, still. I've had stuff snap to non-existent monitors before.
