I have a problem. When I want to export the document, there is always this message: Can not open the file,, untitled - 1.epub,, adobe indesign May not support the file format and plug-in that supports the file format May be missing, or the File May Be open in another application.
Before I did not have this problem and when I exported some document, it was opened in Adobe Digital Editions. I do not really know whether I have done something wrong or what is the problem. Could You please give me an advise how to reset it or how can I repair it?
I have CS5.5 7.5.2 Windows.
Many thanks for help!
I don't do ePub, so I'm not really qualified to troubleshoot most epub problems, but if this just started to happen, I think there's a chance it might be fixed by repalcing your prefs. See Replace Your Preferences
