Error when starting Chat

Hi,
When comming to the home/start page in Zoho chat I get an error message saying "TypeError: this.MessageObject has no properties". The message keeps comming back again and again. Seems there is some bug when loading the page. I have tested both IE and Firefox - problem in both.

A few weeks ago when I tested the last time to login - this problem didn't happen. I don't have any problems running Zoho Writer etc.
