Error Copying Global Layer

[Doc12345]

Hello,  I just purchased Wings over Flanders Fields and when trying to start a mission after creating a pilot dossier I receive the following error message:

"`Error copying Global layer - Make sure the Mission Builder is not running."  The game then takes me to the main menu.  Any help would be appreciated.

For the record (if this is Ricardo) this is sorted now. Ricardo found the solution involves Norton Anti Virus 'Life Lock'.  If you receive a pop-up stating "suspicious activity", click on it and exclude the "action" .
