Hi Ragriz,
Since the latest Addon Manager fixed the issue for KSaunders, I would like to have a look at your DLL.XML file, to see which other modules you have installed. Maybe there's a conflict with something else we don't know yet.
Go to your %APPDATA%\Microsoft\FSX folder, open DLL.XML with notepad, and copy its content here, or send me a PM or an email with that file attached.
