PowerGEOPAK SS10 is not reading Xin preference file

I working on setting up a workspace for PowerGEOPAK SS10 using my current SS4 workspace.  I can't get it to read the .Xin file.  When I try to create cross sections the preferences dialog box is empty and the save, save as, and delete are all greyed out.  The variable CIVIL_XIN_FILE is pointing to the correct location.  What else could be cause the preference to not be shown?

Thanks
