Hi Umberto,
After updating from 1.1 to KLAX 1.4, I can no longer start FSINN from within FSX. When I try to start the program nothing happens then FSX crashes with a APPHANG problem. I uninstalled and reinstalled as per your recommendations. To ensure this was the problem I restored an image using Acronis of my system before the install of KLAX 1.4. All OK. Then I uninstalled 1.1 and installed 1.4, again as per your recommendations. Again when trying to start FSINN I experienced a crash. I restored the system back to 1.1 and everything works. Seems to be associated with the new version of addon manager and coualt with the 1.4 installer.
Thanks
Andrew Dixon
