Unfortunately not learned from mistakes

I am a tax normally, Steuerlaie and use this software for many years, and for years I have always problems with it. Initially, there were problems such as pure software compatibility errors with browsers and operating systems of Windows and Elster. Which are fortunately gone over the years. Later, it was "only" content bug of the software itself, for example, explanations and knowledge of the program are complex but flawed. In other words: to do things that were really clear I read further information and ultimately I do not know what to check. A new tax year means to me has always a computer all day. And at the end remains the uncertainty as to whether I have really done everything right ... and that may cost money - but in any case my nerves.

By the way: In the Help area one finds recently striking many spelling mistakes! Yes, it works but not at all well. Yes, the only support staff have set for now?

Now everyone is wondering why I did not just try a control program to another company. Right. But then I have to return to a new, intuitive probably just as bad, incorporated software, like for example from Word 97 to Word 2010. And security is all this to me either.

In version 2014 tax year 2013, does not work "This question I do not understand" function !!! Because this software more insecure than enlightens me (it's driving me crazy!), Therefore only 2 stars. It can not be that hard for such a company to make a good software, right?
