connection pc texas titanium ti89

[Teopado89]

hello to all are in the high sea:
years ago I used texas ti89 calculator for mechanical foundations.
Now I've got her back in my hand because I'm going over the state exam.
not having the program in the calculator anymore I need to reinsert it.
Then I reinstall the calculator on the pc, only that in the end tells me that the drivers are missing and when I connect with the pc cable and calculator, the pc does not detect it.
Will you please help me?
PC:
Windows 7 operating system

calculator:
ti-89 titanium
os version 3.10,07/18/2005

Have you tried to search for drivers on the internet on the texas instrument site?

hi, I tried to search on the site, they said to download a version with beta patch for win 7 and directed to the download page where I thought I downloaded the program first.
Well now with your new computer program you see the calculator:-d

new problem:
I tried to do exercises that I had done years ago (I have sheets with es held under hand) but every time I use newton rhapson for position analysis tells me singular matrix. . someone remembers why

solved, I indicated the unknowns with x and y, instead you have to use t i-esimo and teta i-esimo
everything solved
