Thanks all for the assistance and support. As of now, the problem has gone away. I removed all my snipes, waited until after midnight, and then logged back into eBay. The number check box was no longer there and everything seemed to work fine from an eBay standpoint. I went ahead and verified my password on AS as being correct, which it was, and re-entered all of my snipes. Successfully functioning once again. Still have yet to hear anything from eBay regarding why it happened in the first place and have no way of checking to see if there was an attempted hack on my account. I, being fairly computer savvy and technical considering I'm a Unix System Admin, suspect that something went wrong with eBay that looped me and that every AS attempt to snipe was just making things worse. I must say though, for having used AS for nearly two years and only now having an issue, that's a pretty good track record.
Thanks again all for both the welcome and support,
