The most important resource for troubleshooting is the simulator's log file
C:\Users\%USERNAME%\Documents\Aerofly FS 2\tm.log inside the user-folder of the Aerofly FS 2.
This file is a text file and logs all events during the Aerofly FS 2 Flight Simulator execution. It contains warnings and errors that might be generated when the new aircraft is loaded.
tm.log file can be opened by any text-editor and will contain important information about the cause of the crash, usually towards the end of the file. Any “WARNING:” or “ERROR:” messages should be payed attention to, sometimes the issue can be solved by the user by doing so.
When the Aerofly FS 2 Flight Simulator application crashes the IPACS support team
mail (at) ipacs.de) can help better when a copy of the
tm.logis attached to an e-mail to them.
