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

Unfortunately, it often then gives misleading error messages about what is wrong; including quite often a message such as yours.

Try completely removing any authorization using ctrl-shift-D to ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your Adobe ID.
