I agree that the error message is somewhat confusing. What
appears to happen is that the default vce is -vce(gnr)-,
which is a non-standard vce. You can read what the defaults
are in -help nl-.

A more serious problem is that the -predict- function after
-nl- does not allow  the prediction of scores. This is a
requirement for -suest-, so that means you cannot use
-suest- after -nl-.

What you could do is rewrite your two problems as a maximum
likelihood problem, estimate them using -ml-, and than use

Hope this helps,
