I purchased a Multi pack code, that works with all my other AVG products. But I can't get it to work on TuneUp. TuneUp is showing me "DUE NOW" when all the others show me expiration dates. Under subscription, it has an older code that I can't seem to remove to add the new code, even logging in to my email doesn't fix my problem. It offers the option to "Switch to this (new) subscription, But that never works even though it says it did. I even try finding it in the registry editor with no luck. How can I fix this or where in the registry editor can I find the subscription to correct it there?
