I've just updated my Mac to Yosemite and now I can't open a .numbers file I have just updated my Mac to Yosemite and after that when I try to open .numbers file, I couldn't, and it gives me this message "edit 1.numbers can't be opened". 

I do not know why and I really need this file.
Having the same problem and don't have a permanent solution. However, if you email the file to yourself and open it from the email, it will open.
