Why do I receive an "Invalid key" message when entering my registration data?

There are several things that you need to be aware of when entering the license key into the "License Data Dialog". The Name, Company, Serial Number, and Expiration fields must be entered exactly as shown in the registration notice (case is important). For example, the Expiration field should be "Never" as opposed to "never".

The key is made up of the letters A to F and the digits 0 to 9, so make sure that no letter "O"s have been entered in place of a "0" digit. We recommend using CTRL+V to paste the data into the license dialog (you can usually use CTRL+C to copy). Also, after you have entered the data into the fields, make sure that no leading or trailing blanks are present.

If you still get the "Invalid key" message after entering the registration data, exit out of Entunnel™ and start over.
