Carvana sent ny registration packet to my old address

Basically it's my fault, I gave an old mailing address and I'm almost certain they sent my registration documents there. it's been about a week since they sent them and I still haven't received them. how screwed am I? I know they send some papers that I need to take to the DMV here in iowa so I can complete the registration process and get my plates etc. I can't talk to a human until the morning but I'm kinda stressing out since I realized I provided them the wrong address.
