Demo Activation

hello, i am in the last of my degree course. Couple of months a go i downloaded super lab 4 demo version, it has ran out of date, and is asking me for an license number. can some one help me pleaseeee

The SuperLab demo will only work for 30 days on each computer it is installed on. Once the demo expires you will need to purchase a license to obtain a license number. You may place an order by contacting Cedrus at (800) 233-7871.

Thank you!
