YacReader Library Not Showing Cover Art

When I run the YacReader Library the cover art does not show on screen. I get stacked issues of a series with a black outline.

What happens if you update your library?

I have tried to update the library several times, but that has not changed the result. The view is still that of stacked issues with no cover art, just outlines.

As you navigate down through the folders are there any folders with covers? Is the app showing covers for your comic files?

No, none. I have a decent sized collection (98,603 issues). For example, if I go into the DC folder, I see the outlines as described. Whether I just scroll through titles, or click into a stack, there are no thumbnails. I remember this occurring a few versions ago, but it seemed to self-correct upon updating. Uninstalling and reinstalling has not solved this one. The process of rebuilding or adding a new library is tedious, so I am looking for other options before going down the uninstall/re-install route again.

Are there the cover files in: your_library\.yacreaderlibrary\covers ?

Yes, there are. Over 8GB worth.

Could you share the full path to your library? like c:\blah\blah...

\Collection
\Collection\.yacreaderlibrary

Does the cover flow view work?
