The first thing I would try is disabling Suitcase....
Thank you or the reply, I will give it a try and advise.
Hi again Peter, when you say disabling Suitcase I am assuming that you mean either deactivating the font or closing the program. I tried both - no change, same result.
I have been going through the steps that took place to get into this position, all I can put it down to is a syncronisation I ran last week to correct the page count in the book. While going through the process a dialog box came back advising that there were fonts missing, I clicked "cancel" to correct the missing fonts but it ran the sync anyway, once completed a new dialogue box appeared advising that documents may have changed and default fonts had been substituted. (Minion Pro) Minion Pro doesnt appear in any other part of the catalogue/s.
There is only two fonts missing
Minion Pro (Minion Pro is a default/substitute font on my system).
Continuing on I had one of the other files open which returned the "Font missing" dialog box, the font required was the Mathematical font, I was able to select it without problem.
I then opened the corrupted file and the Mathematical font didnt appear in the list.
I have also uprgaded from 5.5 to CC, no change same message. I have also sent emails to Extensis suppliers of Suitcase - no reply as it is the weekend in the US.
Any additional information or ideas would be greatly appreciated.
No, I mean opeing the Extension manager and deactivating or removing the Suitcase plugin.
