[pstricks] problem with compiling

[Stefano Demichelis]

Hallo,

I am trying run a file in order to build a tree.
It is an old file that, about 5 years ago run perfectly, now I get
244 error messages.

Can somebody tell me what is going wrong?
I am very bad with tex.
I append the tex file and the error message file.
Thanks.
