Hi, I reinstalled the CL650 and am going through the checklists. When I select 'Status' on CDU 1, the CDU displays a blank page, then goes back to the Index page, so I cannot access the Status page. The same happens if I try to access the POST INIT, or IRS CTL page. I am getting a Message in the scratch pad that reads 'FMS Not Responding'. I have tried several times, no luck. CDU 2, on the other hand, works fine. Is there a fix for this issue? Thanks.
