Noob with a PowerAmp for Android question

Loaded up Poweramp on my Droid Razr this afternoon. Everytime I select the app, it opens the website page first and says to install it. Once I do that, then the app comes up. I purchased the full version. How do I uncrack this app?

Thanks!

ps: it may be possible that I have purchased a SmartPhone that is smarter than me!

Did you purchase it from their website or from the android market? I would contact the developer and tell them the problem you are having, their contact email is: poweramp.maxmpz@gmail.com
