I have never been able to load a saved flight with the Captain Sim 767. All my flights are done with the Sim Rate set to normal (1x), I might pause FSX, but my computer always remains ON to preserve the flight.

December 2011, an official supporter of Captain Sim, namely Mark, gave the advise to leave the PC on to be able to load a flight.
January 2012, the worldwide energy consumption was raised by 30% over Jan2011 and experts are still looking for the cause.  ;D

Remember, if energy runs out, the machines will do this.  :o
