AAR alpha application different region error?

whenever i click the button to open the application on lodestones main page it brings me to a page where it says that the region is different, anyone have any idea why? my acct is registered in the US, along with being on the US site for lodestone and finalfantasyxiv.com.

Make sure you are in the correct region of The Lodestone.
On the top right hand side of the page you see country flags, try different ones out and go to the test app page.
