Just bought and am setting up a new Windows 11 computer to succeed my dying Windows 7 machine. I installed my old copy Directory Opus 12.24 (downloaded previously from your website) and imported my program certificate, and it worked well for a few days. This morning, however, I started getting the "integrity check" error and DOpus will no longer load. My first thought was to replace 12.24 with the most recent version (12.26), which I did, but still no luck. How can I fix this? I am utterly dependent on Directory Opus for file management and navigation.
(If it makes any difference, note that this new PC has not yet been connected to the internet, which won't happen until I can move this unit into the room with the router. Does the authentication process require being online?)
