No significant computer program can be guaranteed to be free of problems, especially one that runs on Windows.

We are not foolish enough to say that. However, we try very hard to make sure that our programs are as problem-free as we can make them. This includes having people outside of our company help test new programs.

If you do have a problem, please contact us through Technical Support.

If we find a bug in our program, we will do our best to correct it and send you a free updated version.

By the way, we are always on the look out for customers to help test programs. The pay is pretty low, but you get a big pat on the back from us and the inside track to try to get new features into the program. Sorry, but you have to be a current customer to be a beta tester.
