I can't open any of my excel spread sheets. Every time I try there is a grant access button and when I click on it says the file cannot be opened because it is either encrypted or read only. I go to "get Info" on the file and it says it is read and write so I just do not get it. Can some give me an idea. And I am not very handy around a computer. If I send the files to someone else they can open them
