Report works in .Net 4.0, hangs in 4.5

I have a C# app (originally written in VS2010 .Net 4.0) that uses a Fast Report (V2015.1.1).
It works perfectly.

I upgraded the app using VS2015 to .Net 4.5.

The code still runs fine, generates no errors, opens the window that the Fast Report Viewer is in.
The in-progress bar appears in the window, and that's it. The report never appears. It just hangs with the in-progress bar visible.

Anyone have any ideas why the report is no longer working in .Net 4.5?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
