Delete that file then start up FFXIV: ARR
Deleting that file seems to have fixed everything. Lemme know if that helps, Something though is corrupting it after log out/crashes it seems, but at least it's pinpointed down to that (for me at least).
Good luck I hope that helps! I don't know if it'll save your UI, but it'll save macros because macros are saved in the Macro.dat file in the same FFXIV_CHR<Numbers> folder. I started deleting one by one until I got to control so my UI reset, but hopefully yours saves if you just delete the CONTROL0.dat file. =]
