Popmartijn, you're fine. If you didn't buy JT tix on your current sub, you're in business (and as you've seen, you successfully completed setup, etc. Just remember you have to do this for each date you want to try to get tickets for).
And thegrunter and zoomcat, as long as you didn't use your CURRENT sub for JT tix, you're fine too (although as Bigwave said, you need to setup your verified fan thing--see FAQs on U2.com, your account page, etc.).
