I experience a lot of problems with DRM rights. Is really something doen't work. You pay and you need to be a super expert in order to read a book (and in the meantime you loose more time to understand how to run the program instead of reading the book). My problem now is I have the file and I cannot read it because the ebookreader is not allow to read it. this is crazy matter. I lost 4 hours to try and try.... Thanks for your help
