An error has occurred. 0 Call to undefined method awoLibrary::getDate()

Just updated to the latest release and now when I use the Send Voucher feature, I get this error message upon sending.

Not sure what to make of this, that function getdate does exist in the latest version of AwoCoupon, 2.5.9.2.  Makes me think something went wrong on upgrading.

The file www/administrator/components/com_awocoupon/helpers/awolibrary.php should contain function getdate.  Can you check?  Or if you prefer, I can look at it directly if you can send a private message with temp admin and ftp access.
