.NET Framework error before any elements are rendered

Microstation V8i SS3 8.11.09.608, Geopak SS3 .722

When I open a fresh instance of Microstation. I select the file to work in. All my tools appear and even Civil AccuDraw comes up. And then this error.

When I click continue, of course the automatic reporting windows come up. And then if I click to ignore, it continues to work normally.

This began just this morning. When I left my computer last night it seemed to be fine.

I've found that this error is raised each time I open a different file.
