Samples do not work if I modify them

I was going through the tutorial of direct Rt, but I've noticed that if I save a csv file, it is no longer possible to run the file. Is this due to the fact that I have a try out license number? Or am I doing something wrong here? I have kept the csv format.

This is likely the same issue as above.

This works! Thank you
