problem with chat plugin on a non self hosted server

I keep on getting a 406 error from my host and they have told me that this is since I have installed the chat plugin with the WPMU dashboard widget. I am so frustrated because I keep refreshing my DB to a backup, and I don't even have time remove the plugin.

My real problem is that I am scared I will never be able to run this plugin. I barely got to try it out and the little I tried looked so great!!!!!

My host tells me that this is surely due to a poor coding.

Do you have any solutions for me?

Thank you so much for your help and sorry to have our first contact with bad news.
