Could not load display preference pane Yosemite

I had went into my Display window in System Preferences to change the rotation of my screen, upon trying to re-open the Display window, I get the error Could not load display preference pane. Now my screen is stuck upside down and I cannot fix it to save my life. I tried deleting com.apple.systempreferences and the desktop.db and restarting but it doesn't work.

Please please please help me.

Yosemite 10.10.2

MacBook Pro (Retina, 13-inch, Late 2013), OS X Yosemite (10.10.2)

The file was called com.apple.windowserver.<insert a bunch of letters>.plist

So my only option at this point is to reinstall the OS? :/

Also if this is the case, do you know how I can "back up" all my stuff? Thanks!

Why would I backup using Time Machine, wouldn't reverting to the backup put me back with the same issue?

You're not going to revert to the backup. Without backups, you're in constant danger of losing every bit of data you have, and it will happen eventually.
