Your current subscription is still active until July 26. In order to get a "valid" transaction page with credit card option, you must select the same time period to extend the current subscription (indicated by *). If you want to switch to a different time period, either 1 year or 6 months, you'll have to wait until the current subscription expires, then order the new one.

The "invalid" error message is because the program only allows one subscription type at a time
