The Statalist FAQ does give the advice, etched
into my inner being ever since I wrote the original:
"Say exactly what you typed and exactly what Stata typed (or did) in
response. N.B. exactly!"
I can see nothing in your question even about what Stata commands
you are using and whether they are official or user-written.
If you read through the help for -whatsnew- you will get information
on what has changed in official Stata since the release of Stata 9.0.
Otherwise I suggest that more information is needed.

there is a thing really strange that is happening using either
stata9.0 or stata 9,2.
I am estimating a panel equation where the id is the worker, and of
course t=year.
I do my estimations clustering by the region where the worker works.
(So it is possible that from one year to another the worker can change
region of work).
So, when I use stata 9.0 it does the estimates. When I use stata 9.2
it says "Panels non nested within cluster".
This sentence has happeared to me already in stata 9.0 but only when I
tried to do the regression with lagged variables, so that for workers
changing region it had sense in effect.
What could is mean to you?
What is that the problem?
