Hello Dave,

eBay is periodically rejecting all passwords that are alphanumeric only. To ensure that all your snipe go through please change your password at eBay to be more secure, then update it at our site.

Note: You can check your Completed Snipes tab which usually has a hint of the error condition or why you did not win the auction(s).

Kind regards,
