Viewer not opening any ebooks

jenrar · Yesterday, 07:25 PM

Most of the time, my Viewer won't open a book. First open or not. Occasionally it works fine for a whole session of me opening books (to verify name on cover, read, whatever). But then I go for a while and it doesn't work. Opening it just sits there and "spins" (ie loads).

I've done searches here. I know that it might be a cache problem. But I am absolutely clueless about how to do the suggested move of the cache if that's what's needed.

Most common is the Graphics driver on the PC is old. Try for an updated driver.

(I have one that is so ancient and no updates. Last Calibre VIEWER that worked was 7.16. Main Calibre did still function)

Okay, I just tried updating but it says I have the latest updates. All my PC updates are up-to-date, including the graphics driver.
