Startup Error

I recently had to replace a drive on my computer (Windows 7) which required me to reinstall BeerSmith. After downloading and installing the the program to the default location I get this error message at startup (see attachment). Drive D: is my optical drive. Thinking maybe some of my default file paths might be off in Windows I tried uninstalling BeerSmith and upgrading to Windows 10. After reinstalling BeerSmith I still get the same error. I tried clicking through the error and when the activation screen comes up it says I have over 1 million days to activate. I tried entering my activation key and the program opens but upon closing and reopening I get the same original error and the prompt to activate again.

Has anyone else run into this?

I figured out how to correct this. I uninstalled the software then went into the registry and deleted every entry containing Beersmith. After reinstalling everything work as it should.
