It took us a while to figure out the source of this error message, as usual we rounded up all the usual suspects but turned up no leads.

By chance I unexpanded his screen which was stretched to the second monitor to fit on to the one monitor and the error disappeared.

so for the few who have the luxury to work with 2 monitors, be aware if you stretch the transform beyond the 1/2 point of the second monitor and you receive this error message, bring it back in and you'll be good to go. This error message appeared on every job he opened the Transform stage.
