st: dbetafit does not work

[pmunoz@mail.utexas.edu]

I am trying to estimate a model where the dependent variable is
proportion. I downloaded the BETAFIT module and I have been able to  
run the estimation procedure. However, I can't use the "dbetafit"  
postestimation command... I get  message that says "+_b invalid name
r(198)". Could somebody help me with this? Thanks a lot in advance!
