Back with 1.3.2.1 Update

Really excited to hop back on, but I keep getting this message. How do I fix this? I'm using Terraria from steam.

You could possibly be missing some files from you game directory, or could've modified your Terraria Client. I'd suggest you to verify the integrity of Game cache; in case you don't know:

Right-click the game [from your steam library] > Properties > Local files > Verify integrity of game cache

Already knew that, but thanks. I deleted my json and config files and restored them to get my UUID back and now it works
