Saving Flight Plans using the FMC in QW787

Hi 

I have just installed P3DV4.3 64 bit, and installed the great Quality Wings 787 Dreamliner.

When I compile a flight plan in the FMC and Save it, the FMC shows a message saying that my flight plan has been saved,

I fly the flight plan, close P3DV4.

Next day I open P3DV4 and request my previously saved flight plan, but it is not in the stored Flight Plans page in the FMC.

I then check the Prepare 3DV4 flight plans folder, but my flight plan is not in there.

By the way I had the QW787 in my FSX-SE and I had no problems at all compiling and saving, retrieving the flight plans.

I have 2 other P3DV4 users with QW787 who have the same problem. QW forum is no help, no one answers.

Please can anyone help??  (Michael Moe thanks for your input it was most appreciated)
