To retrieve your lost Cartographica key, we'll need to have your email address. Once you submit that, we will send you an email with a valid retrieval code in it. If you have anti-spam filters, you might want to add keymanager at cluetrust.com to your list to make sure that the email from us gets through.
If you have further trouble retrieving your key, please submit a suport request using our support page.
