The odd thing is that I found an old post by Rick that says to try adding "?step=3" to it to continue, and it goes to the page and indicates I have all the necessary files, but when I click on the proceed to next step button, it goes right back to the original check files page again. Happens in both IE and Firefox. The source for the install file shows that the submit button should send me to the next step, but when I look at the submit button in the browser, it only shows it going back to the original update.php page.
