Better Analytics Pro WordPress Error

Been having some trouble with the Better Analytics Pro plugin for WordPress (seeing a "Data column(s) for axis #0 cannot be of type string" message on the dashboard), and just seeing that there was an update released, which I assume should help, but I can't download the update unless I renew.

Do I really have to renew just to get that fix?
Or is there any other way to get my license extended so I can download the update?
