SAS pro freezes when clicking to add scan schedule

[Moley]

I wanted a scheduled scan to run overnight instead of late evening. I removed the only existing schedule and clicked on the Plus sign to enter the new schedule. SAS freezes and the window greys out and I have to exit the program using the exit option from the system tray icon.

 

Restarting SAS and the computer gives the same result - I can't schedule a scan.

 

Any advice please?
