Out of bounds

[Guest]

When  I was in the CURIE, specifically in the hall labeled F-1. 1, I walked towards something which I thought was a window, but was actually a giant hole in level. I started falling out of the level and couldn't get back up, so I quit to the title screen, and entered my save file, hoping I would respawn in the level, but I spawned out if bounds and can't get back it, I'm stuck infinitely falling. Is there a way to fix this?  The attachment I have is a picture of my TV and what my game looks like.
