Here are some things you can check:
1. Time Sync / System Clock
If your machine’s clock is off, activation can fail because licensing validation uses timestamps.
Ensure your system date/time is correct.
2. Internet Access During Activation
Community Edition requires contacting the Wisej license server once to validate the key.
If your network blocks outbound traffic (firewall/proxy), you may see an activation error.
Try temporarily enabling internet access or running on a network without strict outbound filtering.
3. Go to Support -> Account and verify that the license is still active and has not expired.
If all this fails, please email support AT wisej.com with your license key and the error message and we will look into this further.
Please login first to submit.
