I have dug in deeper and the command "TableBorders" is where the issue occurs. There is some difference from the 5.3 to 7.0 startup which triggers the error but only if I edit my document using the custom environment I have set up for my customer. If I open the document "raw" the "TableBorders" command does not issue the warning.
I work in a closed environment so if there is updated documentation on line detailing the startup/initialization process for AE 7.0 can anyone point me to it?
