Problem synchronising

Good morning,
I am having troubles synchronising two tablets with several complete interviews.
In order to synchronise, the application is requesting an update but it keeps failing when I try to do it: It appears to be working, but then it gets stuck on “Downloading, please wait… (100%)”.
What do I have to do in order to get the tablets to synchronise and not loose these interviews?
Thanks in advance,
Frederica

According to your description the problem is with updating, not synchronization.
Try this.
