Blank screen when attempting to view PDF

Question

Using a browser, I go to an link that gets an .fdf file (https://server.com/file.fdf). Inside the fdf file is a /F (https://server.com/file.pdf) call.
If the install of Acrobat Reader 9.3.3/9.3.4 has been done straight from the web, a yellow bar appears asking if you want to trust it once or add the host to the privileged locations, and then the PDF file opens fine.
However, if we use the Adobe Customization Wizard and install Reader via Group Policy, the experience is not the same.  We added the website in question to the Privileged Locations list and toggled Cross Domain Violations, FDF Script Injection, and Data Injection to Yes.  In this case, a blank window opens when clicking on the link, but nothing further happens. Looking in HKLM\Software\Policies\Adobe\Acrobat Reader\9.0\FeatureLockdown\TrustManager\cTrustedSites, the correct keys (cCrossdomain, cDataInjection, cScriptInjection) and values exist, but the problem continues.
If I enter the website into Privileged Locations manually, the same entries appear under HKCU\Software\Adobe\Acrobat Reader\9.0\etc, but the problem continues.
This behavior has been seen in IE8 and Firefox.
Anyone have an idea of how to resolve this and retain the GPO install?
Thanks.

Right now I'll try most anything to resolve this!
1.  The links are dynamic in that the file names have a uniqueid/timestamp every time they are accessed, so putting the whole link in is...hard.  The host name stays the same, thankfully.
2.  Opening the PDF directly works.  It just loses the auto-fill info in the fdf file, as expected.
This may be a red herring, but if I save the fdf to my desktop and then open it, I get an error "Acrobat does not allow connection to: <URL of pdf>".
Thanks for the help!
