[AMOS] Negative variances despite admissibility test

Hi there,

I would really appreciate any help with this. In AMOS, I'm performing EFA. I have selected the Admissibility Test in the AMOS options. However, when I try to see the standardized direct effects, I still get a message saying that:

"This matrix could not be estimated because there is a nonzero posterior probability that some variance is zero or negative."

It then goes on to tell me to select the Admissibility Test, which I've already done.

Any help?
