So, I just installed a bunch of mods and now I get a CTD straight after the loading screen. The startup is fine and I can continue game, it loads, but then before the game screen comes, it crashes. I am using NVSE and the 4Gb launcher, both of which I have ruled out as the cause of the crashes. Here is my BOSS log:

I have been fiddling around with plugins, turning them on and off to try and find out if it is some kind of mod conflict or missing file, but I can't find any plugins which, when deactivated, stop the CTDs.

Any help or advice would be greatly appreciated.

Also, a quick question:

Do 'Dirty Edits' actually need to be fixed or is it just a case of tidying up the code a little to make you feel better? I cleaned files in Skyrim, but it didn't make any difference to me....
