Just wanted to chime in again that I'm very happy with this purchase. GuitarPro has free files pretty regularly, which I rarely see because I'm not in the software every day, but they emailed a few days ago with a free file for something I'm really interested in, Canon Rock (yes I know, perhaps controversial to talk about that one). Maybe I've got no excuse left not to work on that one now. Except of course that I'm working on something else!
Anyway, it's great software, and very helpful.
