I set sample range from 1990M01-2008M12 to estimate the model

automatically set from 2009M01 to 2010M12 in the dialog box and
I click on OK to have predictions for 2009M01-2010M12
(out-of-sample forecasting). There is no option can choose to
generate the forecasts of 2011M01-2013M12.
To get that option, go to the Data menu and choose "Add
observations". Select the number of observations you want (in this
case 36, I think). Then set the sample and estimate your model.
