Error gathering analytics data from Google

[HafnerDesigns]

I have GAD installed in all of my clients' WP websites and have had no problem until now. Each WordPress, Thesis Theme, and Plugin are completely up to date with their current versions. Now, I am getting this message on all sites:

Error gathering analytics data from Google: Error 404 (Not Found)!!1 *{margin:0;padding:0}html,code{font:15px/22px arial,sans-serif}html{background:#fff;color:#222;padding:15px}body{margin:7% auto 0;max-width:390px;min-height:180px;padding:30px 0 15px}* > body{background:url(//www.google.com/images/errors/robot.png) 100% 5px no-repeat;padding-right:205px}p{margin:11px 0 22px;overflow:hidden}ins{color:#777;text-decoration:none}a img{border:0}@media screen and (max-width:772px){body{background:none;margin-top:0;max-width:none;padding-right:0}} 404. That’s an error. The requested URL /analytics/feeds/accounts/default was not found on this server. That’s all we know.

Please try again later.

I've tried the waiting, but that isn't working.

I have done two new things that MIGHT affect this plugin. 1.) I've installed another plugin, "Bulletproof Security", and 2.) set my gmail account up with 2-step verification. I have not seen anything to suggest that GAD will not work with BPS. In fact, GAD was installed first before BPS. As for 2-step verify, I was ready to go log in with an authorized access one time entry password when I found that I couldn't login... I can't do anything. I tried to uninstall and delete the plugin & then reinstall... that did not work either.

I would be very appreciative if someone could shed some light on this for me.

Thanks,

Heidi
