Not that I agree with aimlesscoyote's attitude, but I feel I should point out that I've had this exact same issue and all the evidence points towards it being Awesomemod. My game worked before I went on holiday last week, and when I came back from holiday all I did was download the new version of Awesomemod and suddenly it sits on the loading screen.
And before you ask, yes I do have the most recent versions of all other mods I use, and yes I have checked that those mods are compatible with the current EPs/SPs I have installed and with each other/Awesomemod. I have only updated Awesomemod, and now my game sits on the loading screen. Take Awesomemod out, and it doesn't do that. Pretty sure that indicates that the loading screen thing - for me, at least - is a problem with Awesomemod.

I'm having the same problem with the loading screen. I haven't played in awhile, installed the newest Awesomemod version yesterday and all of a sudden it's stuck. I've checked and quadruple checked everything to make sure it isn't a mod conflict or a framework fail, and I'm up to date on patches. I don't have any ScriptError file either. I've run the game without any other mods or custom content installed and it still sits forever on the loading screen. Uninstall Awesomemod and it's fine again.
