Acrobat Reader X integration with SharePoint 2010

I recently upgraded from Acrobat Pro 9.x to Acrobat Reader X (10.1.2) to test out the new SharePoint integration features. Per the Enterprise Admin Guide, I added the line to my DocIcon.xml file to handle the ".pdf" extension, added the PDF icon to my server, verified that the WebDAV module wasn't present in IIS, and then restarted my SharePoint server.

When I click on a PDF document from a SharePoint document library, however, I receive an error message that reads, "There was an error opening this document. The filename, directory name, or volume label syntax is incorrect."

Some things I have already tried to remedy the problem:

• I have full rights to the SharePoint Server and the document library in question.
• I verified that the WebClient Windows service is running locally on my machine.
• Clicking on "Edit Document" from the document library's item context menu produces the same error message.

What am I missing?

Thanks,

Jeff
