Problem....

The trial version(s) of programs are what is known as "Shareware" offered for a limited time to let you see if you want to purchase it or not. It is kind of like taking a new car for a test drive. The site from where you downloaded it should have sent you an announcement to buy it. All you have to do is use pay pal, or go to their secure site and pay with VISA or MASTERCARD, or DISCOVER, and they will email you a license key to enter to turn on the program completely. Most software is sold this way...so you get to try it out. If you do not like it...merely uninstall it. If yo like it...buy it.
