I don't speak whatever language that is displayed, but looks like you installed a bad extension. Try uninstalling the last extensions you installed, one-by-one, until you don't get that error.

If that doens't work, reintall DW.

Thanks,it's chinese,I speak English badly.
Those ideas you told me,I had tried,but the trouble is still there&#12290;

I'v tried the way you just suggested,but it still doesn't work.there is one way useful that move the file dwscriptsExtData.js of Program Files\Macromedia\Dreamweaver MX\Configuration\Shared\Common\Scripts and opene DW,there is still the same error.then I close DW and move the file back,no errors there after I open DW again.but after I restarted the windows,the same error comes out.
