Shows disappear in a project and even in the back-ups

@cash 

You're partially correct on this issue. While the problem is not directly related to storing a single data file vs multiple data files for a project, the underlying issue might be mitigated by a diversified storage structure. The correct solution here is to find what is causing these project data files to become corrupt / empty in the first place and resolve that detail. Unfortunately, this issue has proven quite difficult to reproduce on our end. We're still looking into the problem, which is at the top of our priority list, but we'll obviously need to get it reproduced locally before it can be resolved. If you should run into any details that might suggest what makes the issue more common, please let us know. Once we can see the issue occur on our test systems it should be fairly straight forward to resolve.

@joshua Tanks for your reply and your attention. I did not use the program lately, due to a lack of free time. I'll give you information of the problem as soon as it appears to me again and I hope you can resolve it.

While I was remixing selected slides from a singel show and change them after applying (time, slidestyle, transition, transition time), the show was empty: 2 kB. This happened 2 times tonight. The bak file is empty and even b.01, b.02 and b.03 are empty. B.04 has content but then I go back in time and therefore I lost a lot of changes.

@joshua before this happened, I added music on the show, the last backup B04 is a show without music. The whole evening I had other  problems: black photos as on no content. I resolved this to add the photo again en after that I deleted the "black" photo. Videoclips didn't play, I had to start over the program for 5, 6 times to see if dit would help. 1 night of work with no results other than a lost show. How is this possible, there are so many issues at the moment... I can send you the map with all the content, it's 2,4 GB.
