The screenshot tells us that MicroStation can't find MDL app. SignCADXM . 
 SignCAD is a separate product to MicroStation, developed by SignCAD Systems, Inc . SignCADXM is layered onto MicroStation: it's a plug-in app. Presumably someone in your organisation is designing traffic signs using their software. 
 If that's the case, then you'll find that SignCADXM is specified as a DGN start-up app. in your configuration. Discuss this with your CAD administrator.
