Problem with the bootstrap

[Luigidigidoo]

Hello everybody:
I made a POPAN analysis, and I'm now trying to make a bootstrap to know if my model fits the data, but when I retrieve the model and press the "test" and "bootstrap GOF" buttons, appears an info window which says "The bootstrap GOF procedure only works for known fate, live recaptures, multistrata and dead recoveries at the moment".
The point is that when I analyse exactly the same datas with the "recaptures only" tool, it works perfectly.
So why it happens? Which GOF should I do to know if my model fits the datas or not?
Thank in advance
