App locks – FX Algebra Solver Review

This application let me try one equation and then an error message came up stating that I only had two more equations I could solve and to press the ok button. No matter how many times I tried to press the OK button it would never leave nor could I even purchase the application. I tried to re download the application but I got the same message and can't even purchase the application. Not developed very well!
