Subject   st: marginal effects after biprobit with margeff

I estimated the following recursive bivariate probit model 

y1 = x1 + x2 + x3 + y2
y2 = x1 + x2

y1, y2, x1 and x3 are binary, x2 is a metric variable. I want to use the -margeff- ado-file to compute marginal effects and the corresponding standard errors. The syntax for -margeff- should be

margeff compute, at(mean x1 = 1 , x3 = 1) model(biprobit)

However, stata produces "invalid syntax r(198);". -margeff- after a simple probit model produced correct marginal effects. 

Does anybody have an idea, why -margeff- is not running after -biprobit-?

Thanks in advance, Jan
