How To Restore Your CompanionLink License
A Microsoft Windows update recently published causes some licensed copies of CompanionLink to lose their license info. The result is that CompanionLink will open as an expired evaluation and prompt you to register or buy the software.
NOTE: This problem only appears to mostly affect systems running Windows 10.
To fix the issue, follow the instructions below to re-verify your registration, which will instantly restore your license. There is no charge for this.
1. Click the expired evaluation message.
2. Hit Verify (note that your email address is already auto-populated in this screen).
3. Your product should successfully register, which restores your license.
