love_and_light, I'm right there with you. I didn't even get a code, so couldn't buy tickets. I suspect that even if I did, my experience would be much like yours and others in this forum. I gave up trying to figure out what was going with my code (or lack of it) and have also resigned to the fact, that I might miss e+i 2018. I know there is still a change that I'll get tickets, so try again on Monday. Again, I'm not hopeful.
I saw JT once at Levi's Stadium and consider myself lucky to have gone. i+e 2015 was a great tour and I was fortunate enough to have good seats.
Alas, my heart
