What happen with my Google Adsense Account?

Today I'm so dizzy....
Why ???
Because today when I opened my email, I found this one from Google Adsense.
The Subject is : Google AdSense Account Disabled

..................................................................

Hello,

While going through our records recently, we found that your AdSense
account has posed a significant risk to our AdWords advertisers. Since
keeping your
account in our publisher network may financially damage our
advertisers in the future, we've decided to disable your account.

Please understand that we consider this a necessary step to protect the
interests of both our advertisers and our other AdSense publishers. We
realize the inconvenience this may cause you, and we thank you in advance
for your understanding and cooperation.

If you have any questions about your account or the actions we've taken,
please do not reply to this email. You can find more information by
