blank download page

Hello!

I have searched high and low for this answer. I have found many with a similar problem, but not the same one! I also want to add that I have solved TONS of other questions by searching for my answer to this issue - so THANKS TO ALL for that!

When I purchase my downloadable item, everything works great. When I come back from paypal and go to actually download the item, the page goes blank and nothing happens. The same thing happens when I go to my account to try to download the item also.

I have looked to see that my items are in the right directory. They are in my public folder under /store/download there are only letters and underscores in the filename. They are set to 775 with permissions (I read somewhere on here to do that) In the admin area it gives the green light when I have added the two item filenames in the attribute things for download.

Hmm.. I have also downloaded the debugger tool and get no errors. When I view source on the download page which is http://www.poshpixeldesigns.com/store/index.php?main_page=download&order=2&id=3
It is almost blank. There is simply

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD>
<BODY></BODY></HTML>

The admin site thinks I am downloading the item because I have only allowed 3 downloads and the counter goes down each time I click or hit refresh.

And finally, when I look at the source code from download.php because I was thinking that might be the page that controls that - it is just commented out things referring to how to get the license if I didn't already have it and so forth...

I hope this all makes sense. I am getting a little frustrated :)
