The Installation/Registration is Super Convoluted.
Does NOT let you simply enter in your key-code in a "request for authorization field" and click submit (the be DONE). Instead, you have to click on a button that says Register & Sign up for their newsletter (were Not interested in a Newsletter). When you do click the button, you leave your WordPress installation and now you're at the BrainStorm web site (you couldn't have it open in a new window or new tab? Not cool.)... But then, it's advising you that you need to buy a license. WHAT!
We have a license! Convoluted as Stupid. Just wont bother to Register because we can't. Oh well.
And BTW, our third browser tab was already logged into ThemeForest and on the product download page where we downloaded the plug-in and paid for it.
Beware, and be prepared to spend some time.
