Before I can even get to the main menu, Skyrim just closes. I have a feeling that this is due to mod incompatibility, therefore, I took some screenies of the plugins / mods I'm currently using, if you can detect any conflicts let me know!

First and foremost, ditch Skyboost. It is completely obsolete. If you are also hanging onto an old version of the game, you need to update.

Thanks for the suggestion, will remove it promptly.

Skyrim is updated, therefore that can't be the problem.

After deactivating and deleting Skyboost, I found Skyrim stil closes prior to opening the main menu.

Skyrim can't be updated. If you were using Skyboost, Skyrim wouldn't even run with Skyboost if it was updated, as far as I know.

Skyrim was recently downloaded and installed through Steam about a week ago, I had to reformat my entire computer, therefore I assume Skyrim is sufficiently updated. All of these mods were predownloaded before the format, and had to be redownloaded upon reinstalling nexus mod manager after Skyrim was installed.
