Works for me, just as for Maarten.

Maybe show your entire code for us to give further advice...

Hi,
Thank you for the quick answer and the tips.
I am using Stata at the office, so I do not know where the xtpqml comes 
from (I actually thought it was installed while upgrading Stata).
I tried your code, and got the same error message as previously 
mentionned, when trying the "est store foo"

"last estimation results not found, nothing to store".
r(301);
