The client and server versions are in sync. Have you escalated this to the hotline?
The only time I see that sort of thing is in alpha software and even then it is pretty rare.
Can you check your silverlight version and see if oyu are using the more current version?
Also, what version of IE?
I have reinstalled FFcore on a new clean installation OS windows 7 SP1.
it functioned fine one day, but now I can't add an imposition step, I get an error message
Am I forced to reinstall FFCore again?
Or is there a solution without reinstall ?
I attached a screen shot to this case.
Thank for your help
