Type -ssc desc ivreg2- to see that you need -ivreg28-, except that you
will need to -update- to Stata 8.2 for that to work. Updating is easy,
free and a very good idea.

I have Stata/SE 8.0 and
I've been trying to estimate something using this syntax for ivreg2

ivreg2 y1 x (y2 y3 = z1 z2 z3 z4) [aweight=w] if s==1, r

or 

ivreg2 y1 x (y2 y3 = z1 z2 z3 z4) [aweight=w] if s==1, liml

In any case, I get the following message
unrecognized command:  mata
(error occurred while loading ivreg2.ado)
r(199);

I've re-installed the package and I still cannot make it work.
Is ivreg2 supposed to work with my Stata version?
