I know your problem is solved, this is more a possible solution for those people who have similar issues and switching polarities doesn't work work.

I pen up the casing and check the integrated fuse, its next to the power terminals on the crio's board. You cant just look at it, you would actually have to check it with an ohmmeter or continuity tester. If that's the problem, you can solder on a new fuse and it would still be first legal
