Please, read the DATE!
Do you see it? it's 08/08, there has been a lot of updates since that time and so it's normal it says "404 not found" you have to search the new address.
(Fiddler, Debugger or any way you like)
I use fiddler whenever there are new patches and updates, but well... seems like blocking and fooling the address won't work(?) or probably I really have to tweak something on it.
