I am new standard user for HP50g calculators. I am as familiar with programming on this calculator. I got the calculator via the company, so I choose the most expensive calculator. I mostly use it for it's statistics applications. Everything worked well until a week ago when I decided to use it for some financial calculations. Since then, I am unable to launch the Statistics application. Instead I get an error message that say BAD ARGUMENT TYPE! This happens immediately i try to launch the application.
I have tried resetting the CAS, MODE, FLAGS, to their default values and nothing works.
Someone please help. If you hang out in owings mills, MD i'll buy you a beer. I am in bind, so any and all help is appreciated. Keep in mind I an not a seasoned user
