TurboActivate Bypasses Prompt to Enter License Code

I use a program called StampManage that uses TurboActivate to check whether I have a valid license (which I do). When I launch StampManage, I get a screen that has a button to "Activate Purchased License Code". When I click on that button, I get the TurboActivate window that says "Activation was successful". But I never get to the screen where I would actually enter the license code and so the StampManage program doesn't launch. I've been in touch with the developer about this problem but he doesn't seem to know what the issue is or how to fix it. So I'm hoping that someone on this forum can help me (or him). I have TurboActivate version 4.3.2.0 on my Windows 10 Version 2004 PC.

Thank you.
