While there is nothing wrong with an 11yr old wanting to learn so much about computing as your sheer dogged enthusiasm reflects, however your stark impatience and tantrum attitude will not get you anywhere sooner.
First you are confused and you need to get your information straight, I don't know what magic anyone told you that specific URL will do to validate you but just so you know web contents change perodically and on a site like Microsoft's, this happens very often depending on the content's subject.
As Bryan hinted, the "blue" alternate method is nothing other than a link that allows you to manually download "GenuineCheck.exe" the hitherto validation executable.
All this changed few months back and what Microsoft uses now is called "legitcheck.hta" and can be downloaded in at least a couple of ways. Ironically the infamous "alternate method" in your head is the normal and most popular route, but unfortunately you want the page to lead you mysteriously someplace else.
Naturally, Microsoft expects you to get to that page from this one and it should take you to what your "blue" alternate method page now looks like today (Microsoft could even change it before you get to read this.....LOL). Now if you click on the "blue" alternate method button, you then get the "Validate Now" page and pretty much all you get is finally the dialog box to either download and either run or save legitcheck.hta if you prefer to run it offline later.
My original response has what may help you, but I doubt you'll ever admit that. You still have so much to learn.
