Our worse mistake in the last year has been choosing WooThemes API Manager for Pro licenses. It’s a total piece of shit. PS — Did I mention it’s crap? 🙂
We’re developing v1.4.0 of Pro right now. When it’s ready, like all new major releases, you’ll get an email with the feature highlights. One of them, is a new licensing API that we wrote from scratch that should solve any goofy stuff with Pro licenses. If you cant activate it now, just sit tight till v1.4.0.
