I received a replacement USB cable. The old one went completely south. I now have two problems. First, I get the error message indicating that the transmitter cannot be found. The second error message I get is that Add-on 3 needs to be activated. When I try to activate online, I get notification that the code is already used. I have Aerofly Pro Deluxe v1.11.07.21. My PC is running Vista Ultimate. Iam using an old JRXF421ex transmitter without the TX module. I have used this Tx before with APD. Here is a pic of my USB cable. Any advice would be appreciated.

Hello mp, let's address your issues one by one:

1) "Tx not found error" - For JR radios, you will need to get a JR adapter cable, AFP-02 or IK31036. The adapter cable need to be connected between your radio and the usb interface cable. Ensure that your radio is in PPM mode.

2) Addon 3 activation error - Your new AFPD interface cable has a unique serial number (displayed at the top right corner of the main AFPD menu). Each serial number can only be registered to one addon. Your addon 3 is still registered to your older usb interface cable. Please PM me the following: your full name, address, email, new usb interface serial number, and addon 3 disk key. I will get a new activation code for you.

Walt, I received your PM. I will try to get you a new activation code soonest possible.

Mike, got the new activation code and ordered the interface cable.

Thank you very much for your support of this community.

Walt

Sounds good and you're welcome!
