dosent HP 50g calculator works properly

Hello! I am a user of the calculator hp 50g graphic and I noticed that it is not working properly... What I mean is that it multiplies bacic matrices write the message 'invalid dimension', which tries to find the det (A) = 0 matrix 6 * 6 with the variable x in its diagonal elements, he finds a degree 16 polynomial instead of a degree 6 polynomial! I am completely disappointed! What should I do?

Thank you very much!!!
