I try to open a book that has been passed to me, and when I try to open it, the Excel (2007) goes gray with everything disabled. The rest of the books do open them. The book that gives problems, does not open in other 2 computers with other operating systems. They have passed me the file (that yes that opens in the pc of the companion that passes it to me) 3 times of different forms and there is no way. I've already tried unlocking it in properties, but it's still the same. The book is protected with a password, but it does not ask for it because the book does not load.
Thanks in advance!
