How do you like YouTube?

The YouTube page in download mode does not display.. there are only a few grey squares / shapes on screen. It also appears a new version of the downloader is available to download however when I click on download, a dialogue box appears stating the web address / link could not be found

When I load the source, i get runtime error. this application has requested the runtime to terminate it in an unusual way. Please contact the application support team for more information.
