Yesterday, I was unable to collect and package my InDesign CC 2014 jobs. This has changed sin three days ago when I was packaging and collecting fine.
The error message reads: InDesign could not package the document 'ZIG-1029 FloorSysLit_12.indd'. Cannot copy necessary linked file(s)
Oftentimes, that means that one of the links contains an illegal character.
Thanks, I am struggling with somebody else old files, I believe that was indeed the solution. I also upgraded to Yosemite
