I just bought a new computer and have well over a thousand editable forms(personal data sheets). I started transfering these files through the use of an external hard drive but when I open them on the new computer I can no longer edit the form and still be able to save it. I get the "this form cannot be saved please print for your records" pop up. Both computers are using readerX. I have the originating computer set to allow changes to the documents but still have this issue.
Sounds like you have Acrobat X on one computer and Reader X on the other.
