First: Twitter feed is a great application ! Exactly what I was searching for a long time ;)

I installed Twitter Feed about 3 weeks ago and everything worked fine.
Until 05/06/2010 :(

On 05/06 I posted 3 articles on my site. All 3 have been published on Twitter, but only the 1st is shown in Twitter Feed.
On 05/05 I posted a new article on my site. This one also doesn't show in Twitter Feed.

I have tried to remove and re-insatll Twitter Feed, but the new articles aren't shown.

Any idea ?

My site: www.grossthiemig.info (Twitter Feed is located in the right box)
Twitter account: twitter.com/grossthiemig

Many thanx in advance (and sorry for my english ;) )
