Want It Now posts - anyone else noticed this?

I put a couple of posts on Want It Now, as I'm looking for some books. Have used it before, no trouble.  Now, I logged in to see if there were any responses to my queries, and the minute you click your entry you get booted out, back to ebay's home page. I notice another ebayer has lodged a Want it Now subject line, regarding access being blocked. I emailed ebay & was told I should add credit card details to my seller account. This - as far as I'm concerned - is rubbish. Has anyone else had this problem?  Are ebay trying to do away with it & not honest enough to just to tell people the truth.
