Have the same problem. The manual is very sparse.
Maybe getting a bit creaky, but cannot see how to save a flight plan . There does not seem to be a hold facility,.
For flying IFR this is needed.
PLEASE consider an up date and can any one help with the above.

Rebuilding system. All is well until I try to re-install 737. I get the following message.
Installation cannot continue. Your registry does not show a valid Prepar3D installation location.
Re installed 737 into V2,5 with no problem.
OS is Win7
Not very technical so simple words please.
