Vista SP1, and Adobe Acrobat digital signatures not compatible

I have a laptop HP with Vista home premium.  I installed Adobe Acrobat 8 professional.  I installed Service Pack 1 for Vista and lost features of Adobe.  Whenever I try to open a PDF with a digital signature, the system freezes and requires a hard restart (remove the battery and everything) to go back.  Given that digital signatures are a part of my daily work, they are required to work.  I uninstalled SP1 and everything went back to normal.  Any update or fix for this?
