Upgrade Plug-ins? InD CS4
I have been sent a file that shows as an InDesign CS4 file however when I try to open it I get the message - cannot open, upgrade plug-ins or upgrade to the latest version.
I've had a bit of a look at the different threads and it seems that it may be that it was saved from CS5 perhaps?
Could anyone please advise me in the most simple terms what I should ask the originator to do to send the file in a readable format?
This is an urgent job and if I can't get it open then I will need to advise them asap so that they can find someone else to finalise it for them.
Thanks in anticipation
Michelle
