I had a crash in wow a few days ago and the bank is now empty i have tried(#48) and i have deleted my wtf and reinstalled the addon but it doesn't work(sorry for my bad english)

Have you deleted your WTF folder while the game was still running? If so, you must exit WoW before deleting any files.

Typing this into the chat may also help:
"/run BrotherBags = nil"
"/reload"

thanks it helped. :D
