Can't manage my files on the mybook live

I moved to a new apartment forgot the CD, so I stetted it up by the WB page and now I can’t manage my files. I have set my user to the admin but it doesn’t work!

 It comes up a warning sign: something wrong with the volume CNID D8 using temporary CNID D8 instead. Check server messages for details switching to read- only mode.  

You may try resetting the unit by holdingnthe reset button in the back for 4 seconds.  If this does not fix the issue you may contact WD Support for assistance.
