I think you're probably experiencing some incompatibility between your version of tConfig and your version of Reborn mod. Mods that rely on tConfig typically have to be recompiled for new versions of tConfig, and I don't think Reborn has been recompiled yet (or if it has, that release isn't official, and it's probably buried deep in some Terraria Online thread).

I suggest going to http://tconfig.wikia.com/wiki/Downloads and clicking on the link where it says "Older versions are available here" and trying older versions of tConfig (try versions 22.5 through 22.8). I'm not sure which ones are compatible with which versions of Reborn Mod currently, as a lot has happened very quickly and the mod team hasn't documented changes well + I can't keep up with them. When I first wrote this blog, Hero hadn't released his 1-click-install version and tConfig was still on 22.5 ... in the past week, tConfig has gone to 22.8, Omnir did a v1.1 release and Hero did his 1-click-install release on his youtube channel...

Alternatively, I recommend waiting for Hero to release the next version of the Reborn Mod on his youtube channel, sometime within the next week or so. Hero has resumed being leader of the mod, so his releases are now the "official" ones it appears.
