Help. I have just bought a new MAC and had all the applications copied across from my old MAC. WHen I tried to use ADE. I got the error #2038. I rang the Ebook seller and they advised me to delete that version of DE and relaunch a another DE which i did. Now i am being told that I should have deactivated it first and then deleted it. But this is after the fact. What can i do now. My ebooks download from the seller as acsm files however when i open the file, it opens DE but does not appear, instead i get this error message( IO error on local file open, Event detail error #2038 ) I am desperate - thinking of tossing this ereader and buying a Kindle. Thanks.
