I solved the problem in my original post by downloading the entire Version 2.2 Build 10 and installing it, but I ran into another problem.
No matter what I do, the editing window remains blank. If I try to open an hpd file, I see the message that the various systems in it are being opened then, at the bottom of the screen, it says "Load OK," but the spreadsheet and side-bar with the short-cuts aren't visible. If I try to create a new Favorite or System, the window where the spreadsheet should be remains empty.
When I exit the program, I get a message that my changes will be lost if I don't save them, so I know the files are being loaded, they’re just not displaying.
I've tried to do a clean install, deleting the entire ARC536 software, rebooting by computer, then downloading ARC536 from your website and installing it, but I'm still having the same problem. I'm running Windows 10 and have installed all Windows updates.
Has anyone else encountered this or have an idea how to fix it?
Thank you.
