I just purchased a Start 11 product key, but when I enter it in the activation dialog it tells me it is not valid, but doesn't say why.
The story is that I'm setting up a new Surface Pro 9 running Windows 11 23H2. I have an Object Desktop sub, so I tried installing Start 11 V2. I set it with taskbar aligned 'Left, Top', which works well on my Dell XPS desktop.
However, with the Start 11 V2 'enhanced' taskbar option enabled, it started randomly(?) duplicating blank taskbar icons. When I disabled the enhanced taskbar feature and restarted Explorer, the whole desktop began to behave erratically, responding very slowly if at all, icons moving, apps flickering, the taskbar stopped responding, and I couldn't get into Settings from the keyboard, desktop, task manager, or command window. This repeated after rebooting again. Both keyboard & touchscreen ceased responding, so I eventually had to reboot into Windows Repair and revert to an earlier system restore point prior to installing Start 11 V2.
I then tried reinstalling Start 11 V2, but the same problem occurred, so I recovered the system, and decided to try the original Start 11. This works fine (although it still displays the duplicated blank taskbar icons when the 'enhanced' taskbar option is enabled) and seems stable.
But when I tried to activate it, it said it couldn't use my Stardock account because another device was using the license, so I went onto the Stardock website and bought another. When I enter the activation code from the email, it says it's invalid.
I hope this explains the situation - can you help?
