I got the same problem, but it was with the old adsense interface. I have 70 $ and they changed to 39 $ !!!!!!!!!!!!!!!!!!
I don't know why some of you don't like the new interface...it's not complicated at all and has a lot more information to help see where you are making money...couple that with analytics and there is a wealth of information available.
You're all lucky people. When I first started with Adsense (1 year ago). I got banned because I purchased paid traffic via PPV, I wish I could go back in the past and fix that, and some other life problems. But you should be happy, Big G giving you new interfaces and updates, better protection etc. Cherish what you have.
Has anyone been banned from adsense with no real reason? Once your domain is banned, I hear that you never can get it again either.
