From CuteNews 1.4.6 to CuteNews 2.0.1

Hello everybody!

I'm having problems while uploading CuteNews from the 1.4.6 version to the 2.0.1.
First of all, I followed the instructions, but when I go to the "Maintenance" panel, I insert the path to old CN directory and an old ID, I click on "Preview" and I get... nothing. The page simply refreshes itself.
If I try ticking "Convert users", "Convert all news, comments, more fields" etc., and then I click on "Do convert", I get a list of green lines, but with a series of "0" next to them. Am I doing something wrong? Is there any other way to transfer all my old news and comments to a clean setup of CuteNews 2.0.1?

Thank you in advance,

Stefano

[EDIT] I solved this by using the absolute path to the old CN directory.
