What Happened to my blog ?

In August I have downloaded Windows Live Writer and posted a single post. Immediatley I have received some error messages to my email account which I cant understand. Immediately I couldnot see the blogs online. I could post them, edit them, almost everything except viewing them online. I even went to see them in Dashboard on Blogger, changed settings, still problem is same. What happened to my all blogs. So far I never posted any objectionable content. Only thing is I used Qumana and inserted some ads. Google dont object any ads as it itself enables to display banners and advertisements and pays commission.
