How to authorize ADE on a new PC?

[ponybear1]

I got a new pc (windows7)..had ADE on old pc. Downloaded ADE 2.0, used same used ID & pw that I used on the old pc. Get Adobe error msg.

"You can only authorize this computer (new pc) with an Adobe ID that has not been used previously used on another pc".

I'm sure this happens all the time, people get new pc's etc.

Any suggestions?

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.
