Lost puzzles after I had to reload the game. I had purchased all of the puzzles too.

Thanks. I did uninstall and reinstall, but I had lost all my purchases; the backgrounds are few and awful; and the puzzle was too small to enjoy.

I tried your link to more complex technical issues. My problem wasn't in the list. Your second link tried to sell me all the puzzles I've already purchased. I started in the Xbox Insider Program Forums a couple of days ago. All I got out of that was
a suggestion to use the Facebook site. So, here I am. If you go back to the forums starting on 28 March 2017, you'll find that I wasn't the only person who had this problem. It was widespread. For about a month, I followed suggestions that the other posters
received. Some had success; most had failures. I got fed up and found my work around. Work a puzzle. Let it crash. Reload and work another puzzle. I uninstalled Jigsaw Premium then re-installed. All of my accumulated puzzle sets were gone. I could
go reload any of them without further payment. I can rework any of those puzzles without crashing. However, they do show that they've been worked. I have bought a few new sets. They are the ones that crash upon successful completion of a puzzle. After
I reload, the box is marked with a star on whatever puzzle I worked.

I have the same problem. When I first got Windows 10, I had no problems downloading any of the puzzles. I had to reinstall Windows 10 about 2 months ago, and since then, I have not been able to download any of the puzzles (99.5% of which I had already purchased
with points). When I try to download any of the puzzles, it crashes.

This may not be a actual puzzle game but Resident Evil had a few puzzles in the game that was difficult.

After working on some of these darn puzzles in Arkham City, I had better be able to do that to the Riddler pretty soon... that's all I can say.
