Cannot Activate APDL License to work PDA Wizard


Mar 15, 2004
Fountain Hills, AZ

I'm still trying to get the PDA Wizard to work. As you recommended, I just purchased the Logbook Pro Professional Edition upgrade ($39.95) and installed it. It shows I have the PDA Companion license activated. (but not the Airline Pilot's Daily Aviation Logbook)

I bought the APDL Palm software Version 4.31 on July 22, 2004 and have a valid user name and activation code. Just to make sure I had NC Software send me all my various registration numbers. They matched.

When I tried to activate the code for APDL on the PDA Wizard Page, I got the error

Run Time Error "9"
Subscript Out of Range

And then the program locks up permanently.

What am I doing wrong?


Hello Steve,

Please submit a support ticket to sales with your prior registration information. Version 6 of APDL is required to sync to Logbook Pro. If you purchased APDL on or after 1 June 2003, it is a free upgrade, otherwise I can give you a $25 coupon towards the version 6 as a courtesy upgrade.
