st: problems with xtabond2

["Eleonora Bartoloni06" <Eleonora.Bartoloni06@phd.wbs.ac.uk>]

Dear all,

I have istalled the xtabond2 package (2.1.2, 8Jan2006) but the program does not work.
This is the output obtained by a tutorial exercise:

 webuse abdata

. xtabond2 n L.n L2.n w L.w L(0/2).(k ys) yr*, gmm(L.n) iv(L2.n w L.w L(0/2).(k ys) yr*) nole
> vel robust
                 <istmt>:  3499  xtabond2_mata() not found

I have Stata10 version installed and the package seems correctly installed

Is there any solution?
thank you
Eleonora Bartoloni
