Suddenly Products Not Showing Up !!

Hi,
My frogle feed shows 633 items with no errors. But when I click on the
"View On Froogle" Link it shows 293 items. When I search froogle the
items are no longer showing up. This feed has worked for months, then I

noticed that I stopped getting orders. That is when I started to look
into the feed and noticed that only 293 items are actually appearing.
What happened to the other 325+ items. Again, the feed shows no errors
and the feed has worked for months. someone please advise.

Also, the security certificate for the Froogle control panel shows
expired warning by Windows XP .

thank you, Frank Caliguri
