Avast SecureLine VPN for Windows "Max Connections Reached" message

Several days ago I started having a problem starting the Avast SecureLine VPN. Received a “Max Connections Reached” message telling me to log out of other device or upgrade subscription. I do not have another device! Am using Windows 10. Help!!

Did you buy from Avast directly or from a reseller…?

I purchased directly from Avast. Have multiple Avast tools actively used.
