Infinite Loading Loop (Before the Menu) - What to Do?

Hey everyone, I have just finished setting up my custom modlist and immediately got hit by the dreadful infinite loading loop before the menu. This also means I don't really have a crash log, because there technically isn't one.

Any advice on which mods in my modlist might cause it? Thanks.
