This sketch is no longer here error

I get a "This sketch is no longer here" error when trying to open a sketch that I have been working on recently. I've reloaded the site, rebooted my PC, but I still can't open the sketch even though it's still listed in the Sketchbook tab. Anyone have a workaround or fix?
