No, that's not the last version. It lacks several changes and 34s modifications that were introduced later. The final version (AFAIK) is found in the library folder of the 34s package, and it's called polyroot.wp34s.

As far as I remember the program seemed to work fine. Maybe there is an error in the code you entered?
