Can you get to your “My Snipes” page? If you can, then you’ve entered the correct ID/Password for AS. But, there might be the problem that your AS ID/Password (nothing to do with this forum) doesn’t match your current ebay ID/Password. The way to check that is on your “My Snipes” page, towards the bottom you’ll see Note: Click the Verify link to make sure Auctionsniper has your proper eBay information to place your snipes.
If it’s incorrect, then go to My Snipes, then Modify Account and enter the correct “Account Information”.
Also, on the sign on, there’s a “forgot password” (or something like that). Only problem, you might not get a response until Monday.
