Dear sirs:

I usually work with Stata 7.0, and I would like to ask you a question.
After estimating a panel data model with fixed effects and with
instrumental variables (command xtivreg, fe) Ive have problems in order
to use Sargan test. Specifically, after running this test, the program
shows me the following message:

" overidxt
overidxt requires version 1.1.4 or later of xtivreg
type -update query- and follow the instructions to update your Stata

Ive receive this message even after updating the program on line with
version 1.5.0

Please, could you tell me how I could solve this problem?

Thank you very much in advance
