What happens when try to move the files to the ebook reader?
I tried renaming the file, but it still didn't work. Then when i went to
uninstall again, i had to go file by file to ensure i got everything.
When I reinstalled AFTER deleting EVERYTHING to do with Adobe (including my
downloaded books), it was the way it was supposed to be.
Since I uninstalled/reinstalled several times before, i thought Adobe
might have sent a patch or something.
Hopefully everything stays this way!
Good luck guys!
