Hi Opperman,
Have you ever purchased our program? If so, you can retrieve your serial number with your order email or order number by yourself at
http://www.cheesesoft.com/support/customer-area/member-login. Once you have found your serial number, please directly copy and paste it into the registration blank to avoid a manual mistake because it it is easy to confuse the letter "I" with "1"(one) and "O" with "0"(zero), and all letters in the number should be capitalized and the dash can not be missed.
If you just want to get an one-month-free trial license, or still fail to log in with your serial number, please directly contact the customer support team.
Thanks so much!
