Hey fellow simmers! I was loving AIG's traffic manager and traffic controller applications until the traffic controller application just completely stopped working. 

1. I do have a shortcut established with the -MSFS2020 tag applied and it is set to run as an administrator.

2. I have the AIG Traffic Controller set to run as an administrator.

3. AI Traffic Manager is working just fine or appears to be working fine.

When I start the shortcut, nothing happens. Not even the splash logo appears like it does in the Traffic Manager. I check on the event log does provide a .Net error.

Application: AIGTech - Traffic Controller.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Xml.XmlException
 

I could provide the rest but will be happy to provide all of the text. But basically it looks to be an XML parser issue, possibly via GMap.NET.WindowsPresentation.GMapControl called in the startup configuration of the App.Main() function. I won't get into it any further here. A windows update did occur around the same time this looked to start happening. Which also was around the same time that the "Maverick" update in MSFS showed up. However, this was happening before I actually downloaded and installed that update. 

@lsteffensen, you might want to post your question on the official support forum.
