I've had a new computer 7 months and had to use dell repair facilities to make a correction. I lost my ability to sign in to my ebay acct. Called ebay spoke to an adviser. As I spoke to the individual, which I thought allowed my ability to sign in to my acct. I got off the phone, tried to get into my acct, my password was no longer locked in. How can I RECOVER my ability to connect. I DID CONNECT, MY NAME WAS ACKNOWLEDGED IN THE EBAY FORMAT, CHECKED IN, TRIED AGAIN, IT WOULDN'T WORK. SAME LOCATION.

Are you referring to a mobile app? If yes, please provide the version of it.
Also, you did not provide your eBay user id for me to check. Please do.
