newbie problem

So I have followed the quick guide, but m,ust have missed something as I cannot get demon souls to work, It says boot successful, but also says :Invalid disc directory for the disc game BLES00932. 

I have tried putting it in a different directory within rpcs3, but it doesnt work. Also the file ps3_disc.fsb only has these text entrees in it?  .SFB
                          HYBRID_FLAG                  TITLE_ID              .

Validate your disc dump with PS3-ISO-Rebuilder on http://jonnysp.bplaced.net/
