My UG is stuck

Okay, my first UG NX post. Well, we have UG NX4 and TeamCenter and we open our UG files through TeamCenter. We have startup scripts but when I got to a certain point the Command window just hangs. It is the process UG_remote that is the culprit. I kill the process and then all is well. Not stuck. The cause of all this was a failed startup because all of our network licenses were used up. Good to know for next time.
