N5230A PNA with 85093C E-Cal

We purchased the above hardware.  The E-Cal works perfectly with the current firmware A.07.50.37 (the latest for the "A" version hardware).  My problems occur, because we must have a setup with an earlier firmware version of A.06.03.05.  We have removed the latest firmware using "Add/Remove" utility supplied by Microsoft.  We successfully added the earlier firmware.

When we go to calibrate utilizing the E-Cal referenced above, the E-Cal wizard does not list the E-Cal.  It cannot find it.

I have tried removing the E-Cal driver and reinstalling it to no avail.  Windows reports the driver functioning correctly.

I have searched Agilents website for information the help and haven't been successful.

Does anybody know if the 85093C can be made to work with the earlier firmware?
Do I need to purchase another E-Cal?

Thanks for any help,

Paul
