Chelicerate

I, too, am having this exact issue. Didn't attempt to deactivate crafting table 2, but i used both my old nether and End files, and then deleted and attempted again. Any help would be appreciated.

Not sure how much of it is relevant, if more information is required from the log, i would be happy to paste it or upload it to dropbox, or something along those lines.
