i noticed the program seemed to be auto saving my work...
Don't assume anything. Always, always save your work regularly with Ctrl+S. If you don't, you're asking for trouble.
I often save multiple versions of the same project to revert back to if needed. You can never have too many backups when things go horribly wrong on you (power failures, computer glitches, mutant zombie attacks, etc...). There's nothing worse than losing an entire day's worth of work because you neglected to save backups.
Adobe should get with the program and develop a robust crash recovery system with automated backups. In spite of being the flagship photo program, Photoshop is still in the dark ages in many ways!
Auto file recovery in Photoshop and Dreamweaver CC work just fine for me. I know because we've had some power outages lately and as long as my opened files were saved beforehand, they were restored.
Acrobat Pro can recover files too.
InDesign is great at recovering from crashes, and the feature is in Illustrator as well.
Without knowing your program, you might glean some information in Preferences. (Application menu on the Mac; Edit menu on Windows).
As Nancy said, always Save. On a Mac, though, it's Cmd + S.
