We are brand new Prepar3D users (version 4) and have purchased the iFly 737NG addon along with the Navigraph Ultimate subscription. However, we cannot seem to get the FMC to recognise the AIRAC data. It appears to be installed correctly:
…but the FMC says DATA BASE INVALID:
Being new users we are a bit unsure whether we have done something wrong in the setup/installation, or whether there is an actual known issue here. Searching the forum we found this post AIRAC 2102 for IFLY NG737 "data base invalid" message on FMC which seems related (albeit on FSX rather than P3D) but that looks like it was fixed.
Any help would be greatly appreciated.
