Hello Karl,
Best to try again after 12 hours, and delete your snipes during that time.
The reason is because for your last snipe we just got a login prompt back, meaning eBay didn't accept the login. After the first login failure, then successive bad logins will trigger a Captcha login checker, but only for our IP address. It goes away in 12 hours. So if you delete your snipes and then upload the new password again, it will work for certain.
Usually we can see what's going on from the result pages, but the only indicator was bad password.
