Cascadingdropdown script runtime error Sys.Debug is null or not an object.

I upgraded to the new latest ajaxtoolkit release and now my CascadingDropDown dropdownlist do not work. I receive a script runtime error sys.debug is null or not an object, the examples do not work either.
I have restarted IIS, deleted cached if files dll and pdb nothing has corrected the issue. I see there are other post on asp.net with the same problem has anyone heard of this, if so is a resolution?

I have rolled back to the prior release in the meantime.

Thanks in advance
