I open a 1a, choose convert to 2a and adobe won't no longer do it.
Before I had XP, now I have 8.1
I made a document in Wordperfect 16 (legal version) and converted it to pdf1a and the document opened in Adobe. It was a good pdf1a because adobe shows me the blue ribbon on the top of the page.
Then I choosed for: save as pdfa - with settings 'to pdf2a' and all went good - in XP.
Now I do the same and it is converted to a non-pdfa... - (in XP I made more than 2.000 pdfa's that way)
Prefetch tells me something I just don't understand and ... how do I interprete those prefetch-textes? (is there somewhere a tutorial?
