How do I fix Error Getting licence key E_AUTH_BAD_DEVICE_KEY

[Nige33856398]

I'm using ADE 2 on Windows 7. I downloaded and used one book onto my Nook a few months ago,. Just purchased some more books and can't download them as when ascm is opened I get "Unable do download - Error getting license. License server communication problem. E_AUTH_BAD_DEVICE_KEY_OR_PKCS12."

The authorise computer option is greyed out on the help menu as well. Also the book I had downloaded now has says "license key is damaged".

I do have internet access and have tried this several times. I've got no firewall software blocking anything. Any ideas what I should do so I can actually use what I've brought!?

Thanks in advance,

Nigel

Two suggestions: either/both/neither may work.   Good luck.

ADE 2.0 is very good at getting registrations corrupt.

Try removing all registrations; crtl-shift-D to ADE (cmd-shift-D on Mac).  Respond to prompts.

Restart ADE

Try again to register with the original ID.

There are lots of bugs in ADE2.0.  Try replacing ADE2.0 with the older but more reliable v1.7.2.

Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.

The forum software is sometimes corrupting the link above.  There shouldn't be a blank in 'editio ns.html'.  The following redirects to the same page: http://tinyurl.com/diged172

Brilliant. Thanks very much sjpt that's what I was looking for. Removed and re-authorised and now it is OK again.

Excellent!

also fixed error "License key is damaged" when accessing a file that previously worked.

yes - moving to an older version 1.7.2 fixed the issue.

brutal - going backwards from adobe 4 to 1.7.2 resolves the issue ... thanks to comments in the forum the issue is resolved and no thanks to adobe

I've been trying to sort this problem out but the links above to ADE v1.7.2 didn't work, and nor did lots of others.  Finally found one at Adobe Digital Editions Download  that worked. Downloaded it, sorted the problem and it only took a few minutes - Shame it took me about 3 hours of going nuts to find this site!
