PCI 6281 board does not show up in Labview as having available physical channels

Hi, I have recently changed computers from a Windows XP machine to a Windows 7 machine.  I am running Labview 8.6 (I realize LabView is not officially supported for Windows 7, but most features seem to work fine).  I also have a PCI - 6281 M series DAQ board.  Although the drivers seem to have installed properly for this card, Labview does not see any available physical channels.  The board shows up in MAX under the PXI heading, and seems to have no conflicts with VISA addressing.  I am not sure if the board should be there, as is there no PXI bus in this setup.  I can't see the physical channels with any NI software including DAQ assistant in the main program, or Signals Express.  Any advice would be appreciated.

What version of the DAQmx drivers do you have?  Also did you install the drivers on your computer before installing the card?

DAQmx is version 8.7.2.  Also, I installed the card prior to the drivers, I will try removing the card and replacing it.  I seem to have isolated the problem - my old computer had the card showing up under the heading NI-DAQmx devices, where on the new computer it shows up under in the PXI heading in the measurement and automation explorer.  I'm still not sure how to fix it though.

Got it sorted out, updating to the newest version of DAQmx fixed the strange issues I was having with the M&A explorer.
