I did the following:
- execute Purge_StartALL. Removed Start11 ending with not successful messages. I clean-up Program Files and registry entries myself;
- reboot Windows 10;
- install latest Start11_1.25-j203-Setup_sd.exe software;
- strangely I had to activate the license twice;
- although cleaning up is done, the pin list was not empty. I forgot to clean-up the <user>/AppData entries and decided not to clean-up these entries first and run the tests.
But, now it seems to work in the correct way. Pin actions works (again) as expected. Little bit unclear what was the issue here.
Of cause I am happy that it is working again. Thx for your support on this matter.
