Determine the value of your database
You just sold me a program that allows me to enter tons of data but no way to use that data.
Upgrade to PRO? I just bought a bloody expensive subscription. What is the matter with you? The most basic function of a database is to be able to find things and you aren't letting me do anything of the sort....
So... what does your program do other than waste about 4 hours of my time setting it up?
