求教：导入网络表错误....

我已经将自己做的封装复制到d:\Cadence\SPB_15.2\share\pcb\pcb_lib\symbols中。为什么导入ALLEGRO还有如下错误：RIPUP_ETCH FALSE;
RIPUP_SYMBOLS ALWAYS;
MISSING SYMBOL AS ERROR FALSE;
SCHEMATIC_DIRECTORY 'D:\OrCAD\OrCAD_10.5';
BOARD_DIRECTORY '';
OLD_BOARD_NAME 'D:\ CadenceTEMP\t.brd';
NEW_BOARD_NAME 'D:\ CadenceTEMP\t.brd';

CmdLine: netrev -$ -5 -i D:\OrCAD\OrCAD_10.5 -y 1 D:\ CadenceTEMP\#Taaaaaa01172.tmp
