I just ran a test.
I too was running ver 10.012 and got a prompt that ver.10.016 was available. I made ready a file I knew I had made with the 10.012 ver.
Then I upgraded to 10.016. (on a second computer in the bedroom just in case something went awry)
The computer ran the updater and then it ran a patch
.. You are then prompted to shut down the program and click retry on the prompt box. After the cycle was complete I got a message saying the upgrade was successful. I again shut all down and opened up my file in 10.016
It does work, Everything works as normal.
So not sure why you are not able to open latter created files other than what's been stated above. Probably check out exactly what is ERROR CODE 103
also, I think its something to do with a conflict with Chrome and that may be what the patch was for...Did your updater run a patch?
It's only a draft and not yet complete (a simple peg-board) I may even ditch the idea but this file was created with the latter version and now opens as expected in 10.016
