chat plugin does not work

Hi,

I install your chat plugin, but it does not work, I speak very little English so I do not understand how your plugin works?

Here is the error:

You have installed the WordPress chat plugin. Please review the polling interval settings before using. In MOST cases the default options will work for your host configuration. HOWEVER, in the single boxes Some polling interval is too frequent and Could your hosting account to shutdown your account. Once you-have reviewed and saved the settings this chat messages will no skirt APPEAR.

We can translate your plugin in French with Poedit?

I would turn off my credit card not to be taken after 14 days, how do we do?

Thanks
