If you want to continue using Drug Trak, then it's strongly advised to talk directly to the developers. I've checked their official website and they offer contact options that you can use to get in touch with them. You can either find them below or access the official website.
Contact options:
Call us at (904) 620-4786, Weekdays 8 am to 5 pm eastern, or email us around the clock at orders@iptm.org
Additionally, you can visit their official website to find more about their products and store.
