Drawing cannot be retrieved
I am using Creo Parametric Release 10.0 and Datecode10.0.0.0
The drawing won't open and says "(title of drawing) cannot be retrieved". Has anyone else had a problem with a drawing not being able to be retrieved?
No matter what I try I cannot get the drawing to open. This drawing has many sheets with a lot of information and will take many, many hours to recreate.
