Urgent help needed with YJ auctions!

I need help with Yahoo Japan. :l I'm using the Rinkya middleman service. As soon as I place a bid on an item, a little white window comes up and says "You've been outbid!" and then goes back to the page. I've tried multiple auctions but they all have the same result and I end up giving up. I think that's impossible for someone to bid one second after I do especially when it happens on items that originally had 0 bids when I found them. Is it some kind of glitch? I'm so frustrated ;-;

The auction I want ends in 3 hours so pleeaaase reply if you know how to fix this!
