KLAS Activation

[BigMalc1]

I have recently tried to reinstall this product but Iget an activation issue. Installed as administrator with AV disabled.
Install completes and I open Prepar3D v4.4 and gp to Addon Manager to register the serial number which prompts me to have the code ready.
After that nothing happensand if I select the airport no buildings are present. I have run the uninstall 003 from addon manager but not sure this is altering registry entries correctly.
Your advice would be appreciated.
By the way I purhased this product from JustFlight and after contacting them they reffered me to you.

Be sure you use the installer on our site, some retailers might have provided with outdated download links.
