[Zope] PDF doesn't display page 2?

Hello all, For some reason PDF's viewed through both Mozilla and IE on http://www.houstonpsychiatry.org do not display any page other than one. The files are not corrupt, they display fine when downloaded and viewed with Acrobat. You can find them in the far right column in the Welcome box. Please help, this is a vexing problem. I'm using Zope with Squishdot, fairly current releases. I've been told that the problem is probably not Squishdot. Thanks in advance! -- IV
