I am running Civil 3D 2013 and SSA 2013. When I try to export my storm system from SSA to Hydraflow, I first get a warning message that it can't find a file path (C:\ProgramData\Autodesk\SSA2012\Support\SSA_Mapping Definition_Civil.xml), and then it says it exported OK, but there is nothing in the stm file. Why is it trying to find a SSA2012 file path?
