Error on Opening an Excel File

Good morning guys,
I am opening an Excel file I saved last time but when I opened it now I got an error. (See the image below for the error).
I don't know why I am getting this error since the last time I used the same Excel file, it worked.
Thanks.

Error:

There was a problem sending the command to the program.
