Installation Issue - 'undefined' is null or not an object

Hi,

I've just installed a fresh copy of the latest version, and have not yet made any changes to the fckconfig.js file. Yet, when viewing the sample pages, the below error is given.
I've tried to reinstall the editor, but still got the same error.

Line: 101
Char: 340
Error: 'undefined' is null or not an object
Code: 0

Thanks
