st: XTABOND2: <istmt>: 3499 xtabond2_mata() not found

["Erasmo Giambona" <e.giambona@gmail.com>]

Dear Statalisters,

I get the following error message when I run XTABOND2:  <istmt>:  3499
 xtabond2_mata() not found.

I think it must be a problem related to the structure of my data
becasue I can run the example in - help xtabond2 - without any
problems. I tried tsset the data but this does not help. My STATA 9.2
is up-to-date (July 2007).

I am at a loss. I would really appreciate any suggestions.

Thanks,
Erasmo
