What might be the possibilities of AJAXToolkit not working under aspspider.net?

I have uploaded anything, the program is up and running.

But.... The CalendarExtender is not working, no dropdowns for the calendar.

http://ajaxtoolkit.net/

I've uploaded the AJAXControlTookKit.dll to the bin folder.

Everything else, aspx, js, css, Global.asax, master page, my application.publish.xml and web.config as usual.

Everything is up and running except the CalendarExtender is not there.

Resources up'ed (pngs)

What may be the reasons why the CalendarExtender is not showing when being clicked on the date textbox...

Double checked all the files are present...
