Dear friends. I am systematically having a problem with the Aerosoft A-320 - 321. From time to time the FSX frame rate begins to decrease, and decreases until it reaches 3 fpm, when it becomes impossible to continue. The only solution that I can give to the problem is to completely UNINSTALL the Aerosoft A-320 - 321 and REINSTALL it again. Is there any other solution to the problem?
