installed digital ed no problems,
used adobe id and password,
then tried the link to a book I purchased
- but error message 'check activation' persists
this forum suggested de authorising it and re authorizing Adobe Digital Editions
- tried this and both of these options - would not let me de-authorize and now both the de-authorize and authorizes options are grayed out.
cannot get it to work or download the pdf's.
I just went through this and found the fix in the troubleshooting information on the right side of the screen. It said to uninstall again and then to use regedit to remove data from the programs information under HKEY_CURRENT_USER, Software, Adobe. Not just digital editions but something called Adept need to be deleted. After I did that I reinstalled Digital editions and was able to authorize using my existing Adobe ID and password. I then downloaded a new book from the library and it worked. I think the problem maybe trying to originally authorize without an existing Adobe ID and password. If you do that then it seems you CAN'T go back and reauthorize with an ID unless you erase everything.
