Ok, thanks.

Then start by updating to OS 1.4 :

Finally 1.4 installed succesfully. Should i proceed through tutorial and install ndlesss or can I install newest OS from TI?

You don't need to install Ndless.

Try updating now.
If the latest version (3.9) doesn't work, just install an intermediate version first, like we did with version 1.4.

Thanks a lot, latest version works flawlessly, now i can run programs.
