Digital Editions not allowing me to authorize new computer

[Kara_Martin1]

I have used Digital Editions for a long time and recently got a new computer.   I went to authorize digital Editions on my new computer and it said "you can only authorize this computer with an Adobe ID that hasn't been previously used to autorize any other computer or mobile divice".   I haven't yet authorized 3 computers and 3 divises, so I have no idea why I am getting this error.

When I try and move books over to my Kobo, I am denied permission. 

Could you tell me how to authorize my new computer with my Adobe ID?

Thanks.

Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

Uninstalling and reinstalling does not help.

Unfortunately, it often then gives misleading error messages about what is wrong.

A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.  ***

This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your (old) Adobe ID.

In extreme cases on the mac, the following extra step has helped some people.  Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash. If you are using 10.7, see Access hidden user library files | Mac OS 10.7 Lion. http://forums.adobe.com/thread/1265248?tstart=0
