Hi all, I recently changed my hard disc for an ssd, cloned the new disc but apparently MS office treats this as a new computer and will not let me write anything. I think it is about time I updated my MS Office, I think mine is 2013 and I cannot find the disc or product key. Microsoft say the have no record, but it is old Now the question. If I install a new version on my Mac, will I still be able to use or access what is on my Mac already or will I loose it all?
