"Error type: LoadXML"

Hello, I do not speak English very well, so please excuse the errors. My problem is this: I am trying to run on my computer the example shown in the video and I always get the same error, “Error type: LoadXML. Descrption: Incorrect XML”. I need to do something extra? I just unzip it and try to run the examples, I use win7, and I’ve tried with explorer 9, chrome 18.0 and firefox 13. Thank you very much.

Be sure to run sample by http ( unzip in web folder of some http server and open by full url, not directly from file system )

Also, some samples require database as data source, checke readme.txt in the samples folder of the relate component.
