Hello and thank you for contacting JustAnswer, I would be happy to help you today.
Strange your file would not have been saved to the current date. You can try an Excel Recovery program to see if it can locate the file and restore it for you. This is a trial version, but it should give you enough information so that you know whether or not the file is even there.
i cant use the recovery program
CrossOver cannot run because a required system component, X11, is not installed
its a work computer so i cant install the required component.
Isnt there a temp files or somewhere I can look?
