Well, that's one of the stranger things I've seen for error reporting. I wonder why Win7 reported things in such a obscure way.
Well, it's looking like it was the Sig 09 (System.Xml.XmlException) that is causing the issue here. One of the very first things
that MoreTerra does when starting up is attempt to load from it's UserSettings.xml file. It only saves to this file when the program
gets shut down at the very end.
So with the program crashing before the main window even shows up it has to be crashing when loading this file, which means it
has to already exist. If it does not exist then the default settings are used instead.
So I can not say what is causing the Xml file to crash but I would suggest you attempt to remove the UserSettings.xml file and run
the software a few times to see if it saves and reloads properly.
To do this open up any folder on the machine and change the text in the address bar at the top to /%APPDATA%/MoreTerra/
You could also put this in the Run option on the Start Menu but it seems that is not available by default in Windows 7.
The folder that appears should have a folder called Resources and one called Logs along with the UserSettings.xml file.
Let us know if deleting this settings file clears up the issue. Thanks
