My IT department appears to have just found the solution to this problem. See if this works for you:
Documents and Settings\your profile\Application Data\Adobe\Acrobat\9.0\Synchronizer\resources
Delete the contents of this folder and then try clicking on your review PDF again. This appears to have fixed my computer. I'm gettting ready to go around to other staff members computers in my office to see if this solves our problem.
