Savegame problem: Unloadable savegame due to Courier?

[Xaymar]

The problem: I can't load any other savegame than the one where I am still at the door of Whiterun. Any further savegames will crash Skyrim.

What happened: After I saved, I walked into Whiterun to speak with the Jarl again, but got interrupted by a Courier. I saved after that and all saves from that "standing infront of Whiterun" save are unloadable.

List of mods(that would usually run):

• SKSE
  
• A quality World Map
  
• Better Gold
  
• Dramatic Clouds
  
• FPS Limiter
  
• HQ3DMap
  
• SLoD PnP & Wine Cellar
  
• Skyrim HD Full
  
• SkyUI

 

List of things I already did:

• Launch Skyrim without SKSE (No change)
  
• Launch Skyrim without Mods & Utilites (No change, Physics went 'What am I supposed to do with all these fancy things?' on the infront-of-Whiterun save)
  
• Launch Skyrim with Administrator rights (Crashes before launch)
  
• Reinstall DirectX (No change)
  
• Reinstall Skyrim (Lost all customized options but no change)
  
• Reinstall Steam (No change)
  

 

I'm at a loss as to what's causing it. I've uploaded the savegame here.
