Puzzle did not download or show up on my collections $spring and travel$.

I've got the same problem! I go to the Download Collections page and it shows they are downloaded, but no puzzles are showing up.

I have switched from one computer to another and only two of my puzzle collections show up! They still show up on my other computer. Can I get them on both?

My laptop bit the dust. I want to play my puzzle collections on my desktop but it won't update nor download the puzzles either.

Although I haven't run into your exact problem yet, I have had a problem with downloaded collections: I've completed all the Cityscapes (one of the two free downloadable collections, Food being the other) puzzles on both easy and medium, but did not get
credit in the stats for completing a collection. I've also completed all the Food puzzles on Easy, gotten the Hungry for Puzzles achievement, but did not get credit for completing that collection, either.

Until I have a chance to fully verify that Landscapes and Wild Animals can be completed and that Cityscapes and Food cannot, I'm going to hold off spending my gold on the other collections, or will buy the cheapest one to start off with.

As part of my troubleshooting, I've played everything on Easy two or more times, so I've got some extra gold to burn if I have to delete and rebuy a collection.

Although there isn't a delete function through the normal user interface, I've looked at the user directory folder structure, and there are folders and files for downloaded collections. At some point I'll probably attempt to manually delete and then redownload
a collection to see if that fixes the issue I'm having.

Ditto. My account is also debited the coins but I'm not getting the puzzles. Even tried downloading the Free puzzles. No change. Download bar shows up, but nothing happens. Is anyone in Tech Support reading these messages?
