OH_CARNBY'S PROFILE

Okay, so over the past week I've been out of town and working on a game from my laptop. All is fine and dandy, but when I got back, I transferred it back to my desktop, and suddenly all the Monster Groups, Attributes, Conditions, and Chipsets in the database have suddenly been deleted and set to one for some reason.

Anything I can do to fix this? Or at the very least, a reason as to why that would occur?
