If you received this error, it means you tried to use an FIS certificate associated with a different MAG account. This may occur if you have multiple MAG accounts, and an FIS Digital Software Certificate is attached to one of them.
To resolve, you can use Account Connections to leverage your current certificate for your new account. If your account does not qualify for account connections, a purchase may be required for new certificate(s). Purchases are completed from the Billing & Support Center of your MAG account. Additionally, you need to remove the certificates from your machine. To remove old certificates:
Step 1. From Internet Explorer, go to Tools then Internet Options.
Step 2. Click the Content tab and click Certificates.
Step 3. Locate your FIS Digital Certificate Software and click Remove.
Step 4. Follow the prompts to complete.
Step 5. Close the browser and log into your MAG account with username and password.
