If you are having problems with auction sniper placing bids because of the ebay password, what you need to do is keep everything at auction sniper the same. The user name and password. DO NOT try to change it to match with ebay. YOU HAVE TO change your ebay info. to match auction sniper. For some reason once you have submitted your info. to auctionsniper, it is locked, even if you misspell a word, you are stuck with it. So even if you messed up when you set up the auctionspiper, you have to officially change your ebay username and password to match the auctionsniper info. because it cannot be changed anymore.
I learned the hard way, and had to figure it out on my own. Good-luck!
