I'm having problems with my authorization. I get an error. check activation message and then when I try to erase authorization it tells me to try again at another time

If due to some reason, you are unable to deauthorize ADE, follow the below steps:

Windows:

Choose Start > Run.

In the Open text box, type regedit and then press Enter. The Registry Editor opens.

In the left pane of the Registry Editor, locate the following registry key:

HKEY_CURRENT_USER\Software\Adobe\Adept

Right-click the Adept key and choose Delete.

In the Confirm Key Delete dialog, click OK.

Your authorization will be deleted.

ADE will be deauthorized now.

Now Authorize ADE again.

Reference:

Error "E_AUTH_NOT_READY" | Digital Editions

Hope this works !!
