Server Unresponsive Spark

Every time I create a Conference the Server is not Responding but I am able to access other Rooms and send messages to my Contact list. Please help!

Windows 7 Pro - OS

How exactly do you try to create a room? What server and version do you use? What is the name of your conference service? What version of Spark? Also check the logs at c:/users/youruser/appdata/roaming/spark/logs (check all the logs and look for recent relevant entries).
