short dump:"File "C:\/SQLFiles.LST" is not open."

Hello

I am firs time performing export/import on a win/mssql based ECC system. I have problem when execuring report "SMIGR_CREATE_DDL"

namely I get short dump:"File "C:\/SQLFiles.LST" is not open." As this is an windows based system I entered the installation directory "C:\" which of course is existing

Has anyone idea what can be done

thank you in advance
