I recently bought or purchased a new key for my OA which expired about 3 weeks ago and received the email today giving me my new key which is meant to give me 1yr (365 days) but sadly its only giving me 298 days, when its meant to be 365.
You'd be better off posting in the OA forum http://support.tallemu.com/vbforum/ or contacting OA http://www.tallemu.com/contact.php
Contact OA directly this is not a support forum for them, As we don't have access to that kind of information.
