Check to make sure your batteries are fully charged. If they are fully charged now, you may need to reload the firmware -- I've seen this sort of problem when the protocols and the DFU file don't match if I play with test builds. You may be able to connect as a USB drive to retrieve model and transmitter settings.
Good luck and let us know how it goes.
