Thanks for the advice. I ended up creating yet another screenname with a different email address that now works. And I was able to keep all my contacts through Trillian.
I tried that a few days ago, but the request wouldn’t go through. After I tried a few times, they “froze” it because of too many requests in a short period of time. My account should be “unfrozen” in a few hours, but this isn’t the problem- at least, that I know of.
