Casedo is an offline application, no documentation or annotation loaded into or made in the application is uploaded to a server. However, in order to check that a license key is valid Casedo occasionally ‘pings’ a license key server held by our payments provider, Gumroad. If the Casedo application can’t access the online server for about two weeks, it creates an error code 605 “Offline Expired Error”.
At the moment the licensing server appears to be experiencing difficulties and Casedo cannot connect to it. This does not affect the Casedo application at all, it is simply a licensing key issue.
UPDATE: Our developers have discovered that the way the Gumroad API has been built to connect Casedo to the Licensing Server is no longer functioning as before. They are currently building out a solution and will have it ready for release next week.
UPDATE 08.09.20: Our developers have fixed the problem and have created a new build, v1.4.2 which we will are now releasing.
