Itunes Store does not show lastest podcast but it downloaded

Question

So i am pretty much and stuck on this issue. I have seen a couple of other post but no answers. Hopefully someone can point me in the right direction.
The issue is the Itunes store does not show the last episode by it can still be downloaded and played.
The latest episode the Itunes store shows is 10/17/10 however it has been updated weekly.
Link to Itunes:

I have used a couple of feed validaters and nothing seems wrong to me. Can anyone find an issue i have not looked at? Should i just try to contact Apple Support?
Thanks,
Bob

The iTunes Store caches the feed and checks periodically to see if it's been updated, so there is a delay before new episodes appear: however it's usually around 2 days, not almost a month. When subscribing the iTunes application reads the feed directly, so there is no delay.
Something is preventing the Store from updating the feed. This can happen if there is some oddity in the feed which throws the Store but not the application - usually a strange character of some sort. I looked for something like that in the first episode not to appear in the Store, but there is nothing odd there: you've used dots in the filename of your mp3 file and this isn't a good idea, but in fact doesn't seem to be causing a problem since some earlier episodes do the same thing. Ideally you shouldn't use dots in a URL.
The filename for the episode of 28 November includes the code %3A - this is the code for a colon - you definitely shouldn't have a colon in a filename. However since this episode comes later than several others which haven't appeared it may not be fatal - but it's not a good idea.
The other oddity is that you have two 'title' tags in the top section of your feed, both empty. You did have a title once, as it shows in the Store, but you've removed it at some point so that the feed is not titled. I don't know whether this is sufficient to prevent the Store from updating, but you should definitely replace the title - I see you are using Podcast Maker, so you need to enter the title there and republish - and see whether that helps.
