Due to a recent hardware failure, I had to replace my laptop, which, having a full hard drive, the backup was about four months out of date.  I downloaded my collection from the website, but nothing has had images except for new acquisitions that I did not have on my wish list.

I have twice attempted to refresh the images.  Of 1,014 titles in my owned tab, I counted only 159 that had images after the refreshing of images was supposedly complete., and many (but far from all) of those were the aforementioned recent acquisitions.

I'm not really finding a pattern as to which images have items and which do not.  A lot of my earliest acquisitions (Zardoz, Tommy, Titus etc.) are showing images, but so are items I purchased within the past year but before I got my new computer (Monsterland, Murder by Death, Pitch Perfect 3).  That doesn't really mean much because they basically went in in alphabetical order when I first got DVD profiler,  If I sort by collection number, 1 has an image, there is no 2 or 3 or 8 through 12, but the others are all missing images until #13, and there seems to be no consistency as I proceed farther.

Regardless, the vast majority are failing to download images, and very few were entered by disc ID.

Nothing yet.  I'm not sure how uninstalling and reinstalling would help, since this was a new installation on a new device to begin with.

By any chance did you have the cover images locked on those profiles?
