Hi
I emailed MSN and they have given me the following reply:
".... Occasionally, a website may disappear from search results as we change our website-ranking algorithms. In some cases, search results may change considerably as we test new algorithms. If the placement of your web site changes you should check back in two weeks. It can take a couple of weeks for changes to stabilize...."
Also I checked my rankings in Google for my keywords and I am back up on the 1st page again. So it looks like patience is the key.
