I re-installed with a newly downloaded exe from your website. The version in "About" is still 1.0.0 though.
Now I can use the library but while scrolling down (sorted with date added) it takes very long to load the covers. I clicked on a PDF with only "loading". And then I could see loading the pdf, but nothing happened except that .NET crashed and the app just shows a black screen.
After restarting winpub I just clicked on one of the PDFs in the first row of the library. The PDF also displays as two pages at a time, previously I only tested an epub file. But the text looks rather ugly, which may have to do with the text size. I am not able to use the "ZOOM" funtion on top of the app.
I attached a picture with SumatraPDF (left) and your app (right). You can find the PDF here:

When I click anywhere on one of the two PDF pages shown the app always skip forward. I'd rather that only the click on the forward button does this.
I can't select any text in the PDF. I'm also not able to copy the links.
