This error typically occurs when the software's physical protection key (the USB dongle) is either not plugged in, not receiving power, or is blocked by a software conflict.
Follow these troubleshooting steps in order to resolve the connection issue: 1. Basic Hardware Check
Re-plug and Restart: Unplug the dongle, wait a few seconds, and plug it back in. Restart both the software and your computer.
Switch USB Ports: Move the dongle to a different port, preferably one directly on the motherboard (back of a desktop) rather than a USB hub, which can cause power delivery issues.
Check for Lights: Most security dongles have a red or green LED. If there is no light, the port may be defective or the dongle may not be receiving power.
Test on Another PC: If possible, plug the dongle into another computer to see if it is recognized. This confirms if the issue is with the hardware itself or your specific system. 2. Update or Reinstall Drivers
