I have been using Indesign CC for a month or two now and for some reason it just started crashing when I try and relink a file in a publication I'm working on. It has worked fine up until this point. Any suggestions? I have already tried reinstalling the program and I've even tried dragging/dropping the links instead of relinking through the LINKS box.
From your post it looks like the crash is happening in a particular document while relinking. Does InDesign crash while relinking to any other image file or an image file from a particular location. If it is happening in case of relinking with any file, it would be helpful if you could share the packaged InDesign document so that I can investigate what is going wrong here. You can upload your packaged ID document to dropbox and share the link.
try exporting to an idml and re-opening that again. If there is a bug in your file, this might solve the bug / your issue.
