i have checked silverlight got installed. nicely.
and it loads the 1st animation (circles out to 7) after which i could see any further activity, please help
I was just browsing the demos at http://demos.telerik.com/silverlight/ and they seem to be working correctly (I am working on win7EE with latest Silverlight4 installed myself).
You might try clearing the browser cache and if you are still experiencing any problems, you will probably need to elaborate a bit more on your specific configuration so we can try to pin the problem down together.
