That's the advice I was about to give. Clear your cache and cookies and then log in again at www.google.com/adsense [google.com]. If that doesn't work, please let me know. ASA
If you're still seeing the new, broken page, instead of the old page, try deleting your browser cache and/or your cookies. I just did that and the old page came back.
