st: How to use xtgls, panels(cor) with imbalance panel data

Hi Statalist,
I have an imbalance panel with significant groupwise
heteroskedasticity, cross-sectional correlation, and first-order
autocorrelation.
But when I regress with the command: xtgls, panels(cor) corr(psar1)
STATA give a message "panels must be balanced".
But xtgls , panels(het) corr(psar1) works well.
I wonder how could I deal with this problem?
Thank you very much in advance.
Feng
