st: your Stata exectuable is out of date

[Johannes Geyer <JGeyer@diw.de>]

Dear Stata users,

I work with Stata IC 11.0 (installed on a network drive) and an error 
occurred which I do not understand.

I tried the following code:

**********************************************************************************
webuse abdata
xtivreg n l2.n l(0/1).w l(0/2).(k ys) yr1981-yr1984 (l.n = l3.n), fd
**********************************************************************************

and get 

**********************************************************************************
G2SLS random-effects IV regression      Number of obs   =       611
Group variable: id      Number of groups        =       140

R-sq:  within  = 0.7145 Obs per group: min      =       4
between = 0.9978        avg     =       4.4
overall = 0.9929        max     =       6

        Wald chi2(14)   =       82243.97
corr(u_i, X)       = 0 (assumed)        Prob > chi2     =       0.0000

your Stata exectuable is out of date
type -update executable- at the Stata   prompt
r(498);
**********************************************************************************

My conclusion is: update! But why does this error occur with such a 
standard estimation routine? 
I tried the same code with Stata IC 10.1 which looks even "more" out of 
date and there I get results 
without any complain. 

The problem is, that we work with a many-user  network license and for an 
update of Stata all users need to close 
it which sometimes takes a long time. 

Any ideas?

Thanks,

Johannes
