Well first try the latest release which is 2017.6.
But are you hosting your file on a network drive or shared folder? Do you sync with another system? It seems that having a reminder reappear is really odd.
// Thanks for this. I was trying to sync with the same release on another computer. Sorry, 'hosting my file on a network drive or
shared folder' is too technical for me. However, I have marked both files to don't sync. I have opened main file, reinstated all my
entries, closed and re-opened again and they are all there so I will work only from one file on one computer.
The only reason I had it on two computers was because I had tried to sync it with the app on my Samsung android phone and couldn't
get that to work. However, the small use I would make of that is not worth the risk of this happening again.
Now going to see how to get the latest release. Please reply above this line
I think I see the problem. You can't set two computers to sync as primary sources. You set one computer to sync as the primary. Then on the secondary computer you open a new file as the sync to the folder.
