https://github.com/DMDcoin/Diamond/releases/tag/3.0.0.16newest wallet release
its NOT mandatory to upgrade to 3016
everything 3013 and upwards is fine regarding combatibility
but the latest 3016 wallet is most advanced regarding wallet stability
and handling of power outages without chain corruption
It would have been nice if you hadn't deleted the Windows binaries for the previous version. Silly me.
