Here's the answer.
o, the short result of my call to eBay Tech Support is that the entire problem with my login was that my <U>current IP Address (of my ISP here) was not in the database at eBay as a 'secure' IP address</U>.
The longer version is that I went through eBay.com's Website and found a phone number for support regarding Account issues - 1 (866) 540-3229. I called the number (which Skype indicated is a Mobile number, for whatever reason (now that Microsoft owns Skype, who really knows what is going on with Skype)), was in the hold queue for 20 minutes, then spoke with one Tech Support representative for 25 +/- minutes when the rep said that they were responsible for Account issues, not security issues and then transferred me to a Security specialist. The Security specialist picked up my call immediately. We then went through all of the steps of the problem which has been plaguing me since Friday (two days before) and finally the specialist said that the problem was that the IP address I was coming in through is not in their list of 'secure' addresses. The specialist then asked me a series of security questions (not the ones which we can set through the User Account settings, but based on the account history, I will not go into them for security reasons). When the person was satisfied the I am who my account said I should be, the specialist added the IP address to the list of 'secure' addresses. The person stayed on the phone while I went through relisting the item which I had been trying to list when all of this started (actually, it was listed on Friday and then my account was blocked overnight (Friday/Saturday), the item sale cancelled and all of this security run-around started), and stayed on the line with me while I changed some over stuff in my account for test purposes. The total call took 1:10 hours. I have to wonder if the issue would have ever been resolved online rather than with a phone call. I think not.
