When loading a script saved on the network, I am asked to enter a password when there is no password for the data file and thus I cannot properly run my script.
The same issue can also be experienced while loading files or saving files from network drives or one drives.
Network issue involved with .xls file type
First, try and save the file locally on your desktop and run it again. If it is successful, then try saving your data file as a .xlsx file type if it is currently .xls.
