Hi.
Beginning with mAirList 2.1.39, mAirList 2.1 will only accept updated versions of the license.ini files. The new files contain some extra information about the mAirList releases the license is valid for. The new license file will also work with the previous versions of mAirList 2.0 and 2.1, but not vice versa.
Please request a copy of your new license.ini by entering your e-mail address here: http://www.mairlist.com/en/license/mail.php
Commercial users: Please note that, in principle the commercial licenses only cover the stable release. This is to avoid that a commercial customer decides to use the very last beta version of mAirList 2.1 instead of upgrading to the almost identical mAirList 3.0 (once it is ready), thus circumventing the upgrade fee. Commercial users who would like to continue using the 2.1 branch may contact me and request a special license for that.
