I have been unable to open an Excel .xlsx file sent as an attachment from an Windows computer. I did download the free version of WinZip Mac, and although I can open it, it is a read-only file. I want to be able to make changes and send it back as I am able to with .xls files. Stuffit doesn't work either. Apple support doesn't understand why I am unable to access it properly.
