Macro Stopped Working to Ask for File Location

[ScoutGMa2]

Please help! I've written the following macro and it was working fine until I completely closed my workbook and tried using it again. It now stops and prompts for the location of a file that a formula [=INDEX('[Country Codes recd 022114 (DO NOT DELETE).xlsx] XXXXXCtryLst'!$B$2:$B$5,MATCH(A2,'[Country Codes recd 022114 (DO NOT DELETE).xlsx] XXXXXCtryLst'!$A$2:$A$5,0))] it uses is based on. After I've selected the appropriate file, the macro works fine and will continue to do so until I completely close the workbook again.

Following is the entire macro. Many thanks in advance for any help you can provide. Since I'm very new at this, any advice for shortening this will be greatly appreciated.
