Lost all of my completed puzzles

I've been having issues with my Internet connection lately. The WiFi has been disconnecting quite often. That has happened long after having completed all the Jigsaw Jam puzzles. Now for some reason, all that progress has been lost.

Mine works but I have lost all my puzzles I bought.

Fixed this problem by upgrading my PC to Build 14393 of Windows 10. Was able to play - download - the previous 2 days Jammers that didn't work before. Up to day on this. Now on to other issues - lost all my regular puzzles I downloaded and completed...???

I began playing Microsoft Jigsaw (Classic Jigsaw), since about the middle of September 2014. Sometime in November of 2014, having completed 722 Easy, 722 Medium and 722 Hard puzzles, of the then 49 collections, plus 50 of the expert puzzles, a total of
2216 completed puzzles, I began to have a problem. Some of the puzzles in three categories would not load. I decided to uninstall and reinstall the app. After I was up and running again, I observed that in the statistics tracking section of the game, my completed
puzzles dropped from 2216 to 0 (zero) and my score dropped from 352500 to a NEGATIVE 104410, a difference of 456910 points. I noted at this time that all the stars, i.e. green, yellow, orange and red/purple under each puzzle remained lit up, indicating that
somewhere, the app still knew that I had completed those puzzles.

I started over doing all of the previously completed puzzles for the second time, but noted that in statistics, the number of completed puzzles started reducing. Example, let's say that on a given Monday I completed 12 puzzles. in the next few days, (Tuesday
or Wednesday), I discovered that statistics had reduced the number of completed puzzles by anywhere from 1 to all 12 of those completed puzzles. I tried doing the puzzles again, (for the third time), only to find out that they would be removed from statistics
again. Apparently, there is a limit to the number of times a puzzle can be completed. While this was happening, sometimes the score would also be adjusted downward.

I realized at this point that it would be impossible for me to complete all puzzles and have statistics report accordingly, so I thought that maybe the problem was fixed and I should uninstall and reinstall the app again. This time, the number of completed
puzzles dropped from 2448 to 1008 but my score remained the same. Knowing that I could never get statistics to reflect my actual number of completed puzzles, I tried to uninstall the app completely, even removing files that I found associated with Microsoft
Jigsaw. Upon reinstallation, the statistics, score and lit up stars all remained the same with the statistics in error.

Currently, I have completed a total of 2534 puzzles, while statistics tracking only reports that I have completed 1081.

You just need to complete 1 puzzle every day to get that. However if you skipped a day and come back next day, even if you complete 10 puzzles that day (5 for the current day and 5 for the previous day), the streak is lost and you will have to restart another
one.
