So there are extra things you can select to enhance the product in certain areas of the world. One of them is Scandinavia and northern Europe.
I selected this option but found when I went to check my updates in MSFS2020 the page would not load. Researching this I found that something in my community folder was corrupt.
I moved everything out of my community folder and added it back bit by bit until the problem came back. I found that when rex accuseason was removed the problem went away. So I fine tuned my accuseason installs and found that when I selected the Scandinavian Enhancment option the corrupt file was added to the folder again. When I removed the enhancment, the problem went away.
So all good now.
