Last wednesday, suddenly my AVG program told me that the activation code had expired, even if it's still valid untill august 2016. I've tried reïnstalling twice, bugfixing with the AVG licence fix, asking for the most recent code via Official AVG Support | Help with PC, Mac, & Mobile Products but nothing works. If I fill in the code, it says: "valid code", but when I press activate, it says "invalid code". Please help.
