It is a "warning" message, but not an "error" message. Therefore, you should
still get parameter estimates. However, lack of convergence is often an
important issue. Although in the case of the EM algorithm, it may not be so
serious since EM is notoriously slow to converge when you set a small tolerance
for convergence. You may fiddle with the control options for EM algorithm and
see if you can get convergence. If not, you should contact the package authors.
Hope this is helpful,
