Invalid key / sim crashes

Post by Slayer » Mon Sep 12, 2022 9:35 pm

Several people have had an issue where they install the product fine but then try to use the aircraft in the sim and a message pops up about invalid key.

The problem appears to be that when they filled out the product key during the install they skipped the username box.

This results in the above problem because there is a key but no username being sent to the authentication server.

You can either reinstall it and fill out the information correctly or open the MVA1H.ini with notepad and put in your email on the line that says username=
