What's detailed error you got? And here is about Error: ASP.NET Ajax client-side framework failed to load.
And refer the similar thread
And if it doesn't work for you, you can post the thread to ajax forum

Hope it can help you

you need to download AJAX and have it installed on your servers. Please go to http://www.asp.net/ajaxlibrary/download.ashx

If the website is old, it could use Asp.net ajax 1.0 which requires manual install on Windows 2008 server.
We can give you more accurate advice if you provide exact error message on website.
