Message:

Error check added in for when a link to follow might not exists. The bug was discovered when running Expeditee reading/writing frame through Google Drive for Desktop (because Google Drive and/or in combination with Windows) had renamed a file 9.exp to 9(1).exp -- but it was still linked to 9.exp back in the Web GD interface. In addressing the issue it was also seen that simply the act of have a frame where a link has been incorrectly expressed could also lead to the same Null pointer exception being thrown.
