I am having issues with my openbridge modeler, when I am opening a model weather it is from OBD or OBM I get this error
I am also getting this error if I try to browse for a file in a folder
In the image above, Imperial Standards is my "workspace" and OpenBridge Modeler Training is my "workset". In your case, the workset that you are using is pointing to a folder location that does not exist or that you currently do not have access to at this time.
