So, for my future reference and in case anyone else has this issue, I thought I'd make a post sharing what worked for me. All the ink cartridges had an "X" on them and I couldn't print anything. Anyway, it wouldn't ever let me get past that page into the menu system, it was stuck on that page and the 'how to reinstall' page.

Immediately after upgrading the 3rd party ink cartridges I use were no longer compatible.
