Downloading ePub reader for Playbook

Question

We don't use a Blackberry phone.  We did, however, buy a Playbook.  So if you're in the same position, go ahead and try to buy the ePub reader from this site.  
The first step is to install the Blackberry App World plugin, which we've now done on three separate computers and OSs.  The second step is to connect your Smartphone, and I presume that's a Blackberry phone.  Since we have a Playbook and not a Blackberry phone, we hit a wall.  Apparently we're not allowed to buy the app, although I've read that a fair number of Playbook users actually have this app.  How did they get it?
Added to this quandary is that I've now read in one of the threads below that ePub reader doesn't work on the Playbook (nor is there a Skype app as shown), and if that's true, it would be quite a blow to the faith we had in Playbook when we bought it in lieu of a Kindle.  I'm just thinking ahead here, but there's likely to be an enormous number of upset consumers who fire up Playbooks for the first time on December 25.  There might also be a quick abandonment of this product when they see, as we did, that the Playbook is pretty to look at but otherwise fairly disappointing, app-wise.
If anyone has something to offer about these topics, I'd be very grateful.

Answer 1

I paid for and downloaded this app to my playbook. But it never showed up among the apps on my Playbook. When I go to the App World page and look under My World, it shows up like other apps do, but it is no where to be found on the main screen.  Anyone know what I may have done wrong, if anything?
The creator's website is of absoutely no help at all.
Now that I paid for this and can't use it, (I can't even find it!!!) any suggestions on how to get refund?
Whoa, this App World is scary when it has your payment info.
Thanks.
