Thank you for your reply. I had tried opening the file from all of those avenues before posting, and they all resulted in the same window.
As for your other suggestions, the SHIFT + CTRL worked in resetting my most recent opened files, but I still got that small end window.
When I went into the options, I was able to select the option you told me to, but I (once again) resulted with the same window as the one in my screen shot.
The same day this happened, I came home to find my whiteboard above my computer had fallen off the wall, spilling a few document magnets onto my keyboard. I remote in to my home computer at school (In use a Microsoft Surface RT so I cannot support large programs on the tablet), so while I was trying to open this file, I had no idea I had magnets on my source computer. I save everything to OneDrive (app installed to my computer), so I don't know if this had something to do with it. I had saved the file on the 8th, tried to open it on the night of the 14th, posted this the 15th, and the magnets fell after my post.
