Similar problem here - one minute fine & the next nothing at all in Summary, Sold, Awaiting Postage etc. I had another problem with signing in & being told my eBay ID did not exist a month or so ago but that was isolated to a single computer which needed the cache cleared. This time it is not confined to one computer rather tied to the eBay account. Listings are still visable on search tho' I dont know what would happen if a purchaser committed to buy?
