Your program could still be in trial mode for several reasons.
1. Make sure you are logging in with the same email address you used to purchase the product. Login to topazlabs.com and see if the product you are looking for is listed on the https://topazlabs.com/my-account/downloads/ page. If it is not on that page, then you will not be able to login to that program with that email address.
2. Try logging in to the application again.
