Hello!

I am trying to reproduce (for a publication) analyses that I ran several months ago using lavaan, I'm not sure which version, probably 0.4-12. A sample model is given below:

pathmod='mh30days.log.w2 ~ mh30days.log + joingroup + leavegroup + alwaysgroup + grp.partic.w2 + black + age + bivoc + moved.conf + local.noretired + retired + ds + ministrytime + hrswork + nomoralescore.c + negint.c + cong.conflict.c + nomoraleXjoin + nomoraleXleave + nomoraleXalways + negintXjoin + negintXleave + negintXalways + conflictXjoin + conflictXleave + conflictXalways
'
mod1 = sem(pathmod, data=sampledat, missing="fiml", se="robust")

At the time, the model ran fine.  Now, using version 0.4-14, the model returns all 0's for coefficients.  This does not happen, however, when I run the model using listwise deletion for missing data.  Any idea what is happening, or how I can fix it?  For those wishing to reproduce the problem, you can download a sample code file and data frame from the following two links.

Thanks for your help!
