All hour i save with a new name. I have #1 to #33 and i cannot now open them. I dont use 8.5 any more for the same reason.
We need more information. What version were they created in? What version were you trying to open them in? Are you using a 32 bit or 64 bit version? Are leaving the Compress option on when you save? What computer platform and OS are you using?
If the files were compressed you may be able to edit the file extension to remove the .zip or something. I’ve never had to do it, so maybe somebody here can help. WendyLuvsCats would be someone to ask as she knows how to do it.
