We recommend that you log out of Google and then try the login process to the application site while still logged out. Google often applies security rules that are activated and can thwart login so we first recommend logging out of Google and possibly using a different browser.
If your problem persists please send us an email telling us the following. We can not help you if you do not share these details:
1) What Browser and Browser Version are you using?
2) Did you have problems registering? If yes please describe the issues.
3) Did your problem occur when you went back in to finish an application – when did you experience the problem?
