Great! Now I only wonder why the rescan without zapping wasn't enough, but who cares, it works!

Cool You'll find my address in my profile (click my name).
One more tip: you also wanted to pay a friend, if you click Add Recipient on the Send tab, you can send funds to more than one address at once. This saves a lot in fees compared to making several transactions (and if everybody would do this, it would reduce the congestion on the Bitcoin network).

Glad to help, I love the feeling of finding back crypto, even if it isn't mine.
