I am getting this error as well. Ads are still being served to all of my sites though, which seems to indicate that the accounts are still active (otherwise they probably would not be serving the targeted ads I selected which they still are showing). Could be a Terms of Service Update or something... If that were it, maybe they are going to have publishers read through the new one when it gets updated or something. I hope this is all put together soon, It would be nice if they notified us of these updates prior to them so that we had an idea of what was going on.
It's now 6:20 EST where I am and I have just tried to login and failed. Good to know it's not just me! Anyone in the program: pls report here when you are able to login. Thanks! AmCy
The slow reporting is a bit of an annoyance. I think we are a bit spoiled with the near real time reporting of G... =)
