As
announced earlier, the QAP license server has been shut down on December 31st. Since v11.5, Quick Access Popup reverted to the free software model and a license is not required anymore. The free version contains no limitation, no donation popup window or "Support this software" menu item like the previous free releases. And the latest version includes many improvements and some bug fixes added over the last months.
The error message users of QAP v11.0 to v11.4 now see was written for the situation where your computer could not connect to the license server. But, actually, this is now the license server that stopped responding. You had 14 days of grace before seeing this message and you now have 7 last days before QAP reverts to the free edition limited feature set.
All you have to do to fix this is to upgrade your app the latest release here. Again, the current version of QAP does not require a license ans includes the full QAP features set.
