Do you have the ability to access your site via FTP? If yes, then you need to find the plugin folder for google analytics and just remove it or if you have experience download the old version and it will work as before.
Then you can upgrade if you like, the newer upgrade works sort of. There is no access to analytics data from within your site (like you would have on Googles site, but the analytics info is still being gathered) because the newer upgrade has the URL to approve that portion in the wrong place.
Turns out Google has turned this over to a third party, need I say more.
