You're an IT guy and upgraded an entire company without running tests for a couple of weeks?
An i3 is probably not recommended for this sort of work, but I doubt that's the root cause of the problem. Most problems turn out to be configuration or or software conflicts and without more specific information about waht you are doing when a problem comes up and exactly what happens we can't really help more.
as I've said, there is several problems but the most inconvenient is the constant file corruption. When it is the problem we usually get it back to a last version or slit the file in blocks of page to see if the problem is some linked image or some thing else like it. With InDesign CC we had problems with folders permission because of long path names.
when the problem is with InDesign, at the first we make a system repair. if the problem persist, we reinstall the software. it is the usual, but as I've said, it is not a single problems. is seems to be unstable or something. that's what I am looking for: there is someone that know about a real instability in the InDesign CC 2014 or it should be something else?
we stay with the latest version of InDesign CC installed in all machines, could be software conflict? we do not use it anymore, but if the problems persist we'll going back to this. what do you guys recommend?
Constant file corruption isn't terribly descriptive. Are you saying these files will no longer open after you edit them?
Are older files being opened directly into a newer version of ID? That, in my opinion, is not a reliable workflow any longer. Instead, convert the files to .idml in the original version and open that. If that's not possible, export to .idml as the first step after opening a legacy file, then open that and save as .indd with a new name. Do not overwrite your legacy files.
ok, let me be more specific
some files are getting damaged and when we try to open it in ID 2014 the ID crashes and get closed. Even if the file is opened on another computer. Some times we just get it back to a older version but, in some situations (for example, when we have to close the material and send to another company print urgently) it doesn't fits
i'll try to convert some the files to .idml and open in ID 2014 to see if it's works.
Thanks for your help
