there's no check boxes to the left for Riley on this step

Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
I'll give that a try! I've been using firefox.
Hmm...that's weird but there's another way to do the same thing. Just click on Edit, by her name, and then you'll see a whole page of her info with a Reset Password button near the top and you can use that instead. But can you also do me a favor and let me know which browser you're using? If it's Safari, try Chrome and let me know if there's a difference? Thanks!
