For starters I am using InDesign 5.5 When I open the file, either by clicking on the file through finder or or opening it through indesign I get the following error message:
The document "file name.indd" uses one or more fonts which are not currently available on your system.
I can't press either Find Font or OK - wheel spins then after 30 seconds or so and then I get the message:
The network connection was lost for the file "file name.indd", or the file was modified by another process.
Press OK. Nothing happens. Activity monitor says Indesign is using 100% of the cpu and not responding. The file is on my local machine and nothing has changed on it since the last time I opened it without issues 3 days ago. I'm not running anything that could be using the file or any of the images the file uses. I have downloaded and installed the font that was missing and the error message hasn't changed. Any ideas?
First thing to try is a re-boot...
Try the option: save a copy for duplicate a file
