Starting second leg, aircraft won't move

[deltamike172 2]

I flew the first leg uneventfully using FS2Crew.  PMDG B737-700WL.  

Pushed back and started engines for the second leg.  Once I applied power to taxi, the ground speed on the ND started climbing, but the aircraft wasn't actually moving visually in sim, both internally in the VC or externally.  I saved the flight, and shut down the sim, but the sim crashed upon closing and I got this message.

Sounds like the whole sim went to pot, there.

It may have just been a one off thing.
