....I will-- I'm about to try a reinstall.
Make sure your master battery is on, and try starting with CTRL + SHIFT + F4. FSx like FS9 plays silly beggers when loading aircraft into a saved flight where the aircraft previously was of a different format, ie GA piston or Civil turbine etc etc. Your saved flight probably has parameters that the helo FDE doesn't so when you select it those parameters are not read and it'll die.
I've no idea what format the Skycrane FDE follows (Bell, Merlin, or Hybrid) but some don't fair too well with SP2 or Accel or vice versa, however the key commands above seem to work across all formats but check your master battery or APU, you may not even have key commands listed for those actions, some are not coded by default.
Hope that helps
