I set up a pipe network and catchments in C3D then used the export to SSA function. All imported correctly (except "unable to load background dwg" error). Then when I go to save or open anything the dialog box is glitched. None of the program icons load and the input boxes are gone. Screen shot below. Has anyone else had this error or any ideas what is causing it?
When I open SSA on it's own or open an old model it works just fine.
