ImportText.pl doesn't work

Hello,

I'm new to Krona, and I had a slight problem -- ImportText.pl doesn't work for me. When I initially download the scrip, I got a permission denied message. I did chmod777, and when permission was open the following error message No such file or directory at ./ImportText.pl line 71. came up. I also manually downloaded a new scrip from github, and I still get the error message. Am I doing something wrong?
