Dear Catherine,

The most common user error that I've encountered is the omission of 
error-variance terms from the model (for both measurement errors and 
structural disturbances).

If this isn't the source of your difficulty, then send me the code along 
with an explanation of what you're trying to do (e.g., a path diagram) and 
I'll take a look at it.

I'm sorry that you're experiencing problems.
