1.2 Crashes at Startup

[adpen12]

I haven't been able to play since I switched from the prerelease. 

From the error log:

Unity Player [version: Unity 5.4.0p4_b15b5ae035b7]

KSP_x64.exe caused an Access Violation (0xc0000005)
  in module KSP_x64.exe at 0033:00000000.

Error occurred at 2016-10-15_125850.
C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\KSP_x64.exe, run by user.

Write to location 00000000 caused an access violation.

 

Any idea what's causing it?

 

I've removed all mods, unchecked read-only, and verified the game files in steam.
