Chat on RMS is not working; method getRooms not found

When I try to go into chat, this is what the browser reports:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at modules.chat.video::BxVideo/set modules.chat.video:BxVideo::user()
    at modules.chat.video::BxMyVideo/::afterRooms()
    at flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchEventFunction()

    at modules.chat.connect::BxIMConnect/modules.chat.connect:BxIMConnect::afterRooms()
    at modules.chat.connect::BxChatRMSConnect/::onGetRoomsResult()

And my RMS server reports this:

Error 3215016 SocketAcceptorIoProcessor-0.0< org.red5.server.service.Serviceinvoker.error >
Method getRoms not found in org.red5.server.webapp.chat.Application@948069

Any ideas?

The Chat loads, but I can not get into any rooms and chat. Also, no rooms are displayed. Any help is MUCH appreciated!! Thanks in advance!
