You could open the cRio up and see if removing the case will allow the switch to move. You should probably contact a NI rep for help if you cant get it back. They are very friendly and helpful!

{Disclaimer:I have not done this} Or you could manually break the connection of the dip switch if it does not want to move. This could be done by unsoldering the switch. Make sure you are statically grounded when you open up the crio and that there are no metal chips on the crio as these can fall in and cause a short circuit. We short circuited our cRio last year, so be very carefull.
