Please restore DB from autocreated pre-upgrade back up and retry or contact MMEX support. (???)
constraint failed [2061]:
When I click OK it then asks
Have MMEX support provided you a debug/patch file? Yes/No
It will then just keep repeating itself till I get bored.
I have used MMEX since 2012 through many upgrades some bad most good and I would like to keep on using it, otherwise I will be forced to go to Microsoft Money
