Prediction with !PRESENT and !PRWTS

Deal all:

I have some difficulties in using prediction. In the following
example, the first PREDICT statement seems to have worked fine.
However, ASReml hanged at "Forming     120 equations:  84 dense" when
I chose to use the second PREDICT statement. Did I do something wrong
here? Thanks!
