RSS Feed and Google / Others

Hey guys, i had been posting and updating my word press blog every few days. I had no time to post for about 6 days. Google had been indexing my pages soon after i had posted them from the rss feed, but it has stopped, it only says I’ve posted up to a post i had done a while ago(iron man post)

Even there (when its up) it shows that the last post on my feed was a while ago, but this is obviously not the case

Think maybe theres something I’ve changed? all i remember doing is adding an adsense banner, which I’ve now taken off just incase.
Any reasons that could of caused google and other sites to stop receiving the rss feed?

And any fix for that?

Thanks for any replys
