I am very new to this. can someone please explain how can I open a tns file containing a python program made using TI Nspire CX CAS Student software v5.4.0.259 into my nspire CX CAS calculator, when i open the file it says it was made with newer version of software and cant be opened. on the other hand I have successfully installed ndless and micropythin on my calculator that has v4.5.4.48. but the micropythin is just a blank page and i have no idea how I open the python programs.
please help
