Please update cardPresso to the latest public version, available through the following link:
https://www.cardpresso.com/cardpresso-software/latest-release/
Then, refer to the attached documentation that explains how to correctly format a cardPresso dongle and manually recover its license on Windows and macOS systems.
In case an error message is being prompted during any of these procedures, please send us a screenshot of it, to support@cardpresso.com, for our analysis.
Also, provide us a screenshot of your Windows Disk Management or macOS Disk Utility view, so we can verify how your cardPresso USB is being detected through the same.
You can also refer to the respective technote on how to prevent the cardPresso device from going into a sleep mode and temporarily losing its license.
If by any chance the reported issue persists afterwards, an Antivirus, Firewall, Proxy, VPN or USB encryption tool could be blocking our licensing feature somehow.
That being the case, an exception must be created for the cardPresso dongle, or the device control application needs to remain turned off, at least while our software is being executed.
