i3 8345 says "vehicle not supported" after installing latest update

[faaaaq]

I have a 2013 300S 5.7 AWD, and my i3 has worked perfect for almost a year now. The other day I plugged it into my computer to check for updates, for the first time in a fair while, and it installed some updates. Now, it says my car is not supported. I plugged it in less than a few weeks ago to confirm some settings before I order a custom tune, and it worked fine then, so the update definitely seems to be the reason it isn't working. Anyone know if there is anything I can do to fix? Do you need my XML? Etc etc? Already tried more update checks, both over wifi and plugged in to my computer, and it reports no updates in all attempts. I have tried 10+ times.
