I imagine you have checked the circuit breaker serving the inside and outside units? You could try resetting these to see if that works. Also, have you checked to be sure the thermostat is working properly? Also, have you checked the high pressure switch or for any other reset switch to see if it needs to be reset. You should be able to learn about these in your owner's manual.
There is also the possibility that a mechanical part has malfunctioned, which may have tripped a safety feature.
If it isn't a circuit breaker, thermostat or reset switch, you will need to bring in an HVAC tech who works on heat pumps to properly diagnose and fix the problem.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
