You can check your support period in the ProteusThemes customer dashboard, under My Themes.
When your support period ends, your theme keeps working. You can still activate your license on new websites and you keep receiving theme updates. Only premium support ends: to open a new support ticket you need an active support period.
Single theme licenses
Each single theme purchase includes 6 months of premium support. Next to each theme in My Themes you’ll see how many days of support are left, or “Expired” once it has ended.
To get 6 more months of support, click Extend Support (or Renew Support if it has already expired) next to the theme. It costs $30. If you bought the theme on ThemeForest, use Re-check expiration after you extend support on ThemeForest.
ProteusClub
Your ProteusClub membership includes support for all themes while it’s active. The yearly membership renews automatically unless you cancel your subscription. A ProteusClub Lifetime membership doesn’t expire.
