I have not received the key.

This article applies to the previous 4.01 version and older.

The new version sends your activation email automatically and immediately via an auto-reply.

Please update to the current version, which is the new minimum requirement for activation and support

Open a ticket here at the helpdesk to find out how.

Keys are generated once a day.

There are two reasons you have not received your key.

First -
have you registered your activation code?
We can't generate a key until we have the code to generate one from.

Second -
If you have registered and have allowed a suitable amount of time for the key to be generated and sent but still have not received the key, then the likely issue here is your email service.

Since there is an attachment involved then it is probable that your email setup has filtered or blocked it. Check your spam, junk, trash folders.

Free email accounts are particularly undependable in this regard.
Others like AOL are overprotective and will block attachments.

If you still have not received the key after a few days then you'll need to provide us with a dependable email address where we can send the key.

You will also want to "whitelist" any emails coming from us so that this filtering does not happen in the future
(you'll need to check with your email provider or email program to find out how to do that)
