Hi Alan,
ofcourse, I made a backup of the NavData.db3 before switching to the new version. But my routedatabase was NOT overwritten by the new version; it was encrypted by the new version only and that is my objection in this case. My problem is that I can not edit my database(s) with the help of SQL any more and I do not understand why RB made this impossible.
My route database was all the past years that I am a RB user arranged and maintained, concentrate on my own situation, by my self. So I feel free to see this database as my personal property.
Please do not take this personal and thank you for your reaction until sofar.
