Ray, do you suggest I try re-installing the 5.30.8 driver and give it another try. Should I do an uninstall first, orThere is no need to uninstall first. You can install over the top either going to a newer or older version of the driver.
The same is true for APCC. You don't need to uninstall first when installing a newer or older version of APCC.
