Hi Nicola, the best way to fix these lua errors is to post into the addon comments of the addon affected:

You might find answers in the comments as well, if others got the same problem and fixed it somehow already.
I've taken a look at the code in file DressingRoomUI, line 515, where the NIL error occurs but could only find the value
Code:
local txt = self._msg.options
Something is missing in DressingRooms._msg here, maybe the whole options table or something else.
Try to logout, delete the SavedVariables file DressingRoom.lua and then login again. Maybe it fixes the error.
