"The requested operation cannot be performed on a file with a user-mapped section open"
I have no idea what that means but it might be something else running in the background, like MCedit or another client.

You can try deleting the entire modpack and redownloading. If that doesn't work, it might be something with your internet or just a step you're not doing right.

or before you delete everything, close every other program. It sounds like you have something that the launcher needs that you're using.

Some mods like to say that a severe, deadly error has occured in large red letters when they boot up. It's promising, like AE knows that it's already ****ed up my game by just existing.

There are other things too that appear as [SEVERE] but most of them are just warnings or notifications.
