Thank you for the prompt and complete answer.
It's difficult to respond to posts in which you're reporting multiple issues without a clear question. You seem to be saying that you downloaded folios on your iPad, made changes, and verified them. When you went to Paris, you discovered that the downloaded folios somehow reverted to an older version. And now you're 600 km from your office. Have you tried re-creating the folio? Probably not, because it sounds like your source files are back at the office. We're sorry that you're experiencing difficulties. Please ask more specific questions so that we can help you.
This doesn't help your Paris problem, but in the future you could copy all your source files to a portable hard drive and then "Relink" them in the field. Adobe added this feature recently and it is very helpful for corrections or updates away from the office. I'm not saying you're at fault, and I've never experienced the extreme problem of the folios you've already downloaded not displaying the next day. Are you saying that when viewing the folios on your iPad they were different from day to day or that when you logged in to the folio producer on digitalpublishing.acrobat.com the files said they were corrupted?
thanx andrew, i did not know this so far.
Andrew and BOb: yes As I said on wednesday, all folios were okay (on iPad and computer).
On the day after, they were not. I can't really tell you more indeed.
GOnna reupload everything again.
