Product Not Found Message

Hi,

I have just duplicated a product and created a link to the product however i am getting the message 'product not found' when i know it is there and i can use the add to cart link to get the product in my shopping cart.

Kind regards

Alex

This is the link by the way:
liveelite.co.uk/bournemouth/Bindon-Abbey...s-Retreat/offer.html

I have just deleted and re-created the menu item and now it works, not sure why it didn't before...
