I keep getting a Login "Failed" after using the Diagnostics test on MyiBidder. without passing login I can not use program...

First, please do not post the same question multiple times. That will not speed up the response time, but may add extra confusion for you.

As mentioned in the support ticket, you can reset your sniper's password at https://www.myibidder.com/login/reset
Once reset, don't forget to link your eBay account at https://www.myibidder.com/main/ebay.

After all is completed, you can login to the sniper using your new password.
