I have the same problem on ths installation of My Traffic, as well another addon.
For My Traffic, during the installation, it generates na error sayin: Scenery.exe sttoped working.
After this, the installation is finished, but when opening the My Traffic Communicator, it says we need to open Manage Prepar3D.cfg, and click on green buttom "add my traffic". But the problem is when clickn on Manage Prepar3D.cfg, the following error message comes:
Not possible to find part of the Way: C:\users\i7\App Data\Roaming\Lockheed
I don´t know what to do. May I have some help please?
