Installed it about a week ago, came back, opened it but got the activation screen. Figured I'd re-install with the same program I got from here, no dice. Un-installed completely, re-installed from scratch (with Medicines), opened fine. Disabled auto-updates, closed out, came back in, ran manual updates, restarted. Works fine.
EDITED #1: Updated to Deluxe within TT while doing my taxes. Went fine up until I started the state portion. Threw up the notice to create an account so I can't continue. I know there's a few ways to fix that, one of which is in the registry. I did that once before but had a brain fart and didn't save the instructions. So if anyone knows how or where I can find the steps, I'd be most grateful.
EDITED #2: Having updated the software prior to continuing my taxes, I was surprised to learn that one free state was included, giving me that ability to complete them.
FINAL EDIT: Used eFile. It submitted and was excepted (via email confirmation) without issue.
