Play the World worked fine by giving read/write permissions to the Civ Directory so normal users can play games but Conquests just pops up a dialog box and demands administrative permissions, even after I have granted all permissions on that directory to my normal user account. Any suggestions as to how to fix this?

Sincerely,
Rob Caskey
