Hey guys so i have a problem that i hope u can solve it
I have a TI-nspire version 1.3.2438, and i want to update it because when i write some documents in computer then send it to the nspire, i cant see them because the calculator version is lower.
I tried to update it many times, but while i am updating the computer software says " the operating system file is corrupt or invalid"
can someone help me. Now i am doing documents directly in the calculator(that is very annoying =(
