Difficuult, really difficult. We do not have data, your OS, R version, 
error message (if there is any). It reminds me like if your car stopped 
and you asked by phone somebody a question #It doesn't work?!?!?! What 
answer you expect in this case?

BTW it works as expected

And I have carichi.annui.lav file in my working directory.
 
Therefore you have to check yourself or at least provide some clues.
