Page not found error on upgrade from 2.2.1-2.2.2

When i try to upgrade from 2.2.1 to 2.2.2 i get to the continue… Page and then it opens a page not found page—403.shtml?sess_id=fc37f95b47fd19fb50d00de6a9af9785

but the page has the 404 graphic on it.

Any ideas on what this is from and how to upgrade?

It does not seem to be able to find the backup page just after the check page

moved to correct forum—
