ASCOM driver error

wayne archard

I have an Exos 2 GT PMC 8 mount serially connected to my laptop running Poth Hub with Cartes Du Ciel.  When I click the connect button on the ASCOM pop up page I get this msg: The ASCOM driver report an error. Class not registered and closes the page when I click OK.  I haven't used the mount since last summer but it was working fine at that time. I updated the PMC-Eight Ascom Driver installation today to no effect.  Any suggestions would be appreciated.
