Can′t delete posts from feedburner. How can I do that?

Hello,

I′m a self-hosted wordpress user.

I am having trouble in deleting some posts from feeburner that I have published in my blog. I was just testing my feed with posts but that I don′t really want them to be published, I have deleted them from my blog but still appear in feedburner.

I have read somewhere that one reason for that could be that the feed readers could′ve already cached the items and there is no way to ask
the readers to delete the posts. I don′t know if that′s got to do with this.

Is there any way I can delete those posts !!!!!???

feedburner url:

Thanks for your help!
