Well, on my Samsung Galaxy S7, I uninstalled all previous versions of the Princess programs. I then installed Medallionclass on my phone again. Hoping beyond hope that I'd be able to run Ocean Ready, I logged into Medallionclass and when I clicked "Get OceanReady", I received the succinct note "Could not start OceanReady." I've finally stopped sobbing and wiped most of the tears from my eyes so that I could add my note to this thread. May you all sail smooth waters with your working Medallionclass app.
