Cant delete a recordstore

Question

Hi,
I was wondering if their is anybody that can tell me why a record store that I have created cannot be deleted using the "RecordStore.deleteRecordStore( );" method.
I have written a bit of code which when executed should delete the entire record store "PLAYERSTORE", but for some reason it does not.
My code:
public void deleteRecordStore()
          try
               System.out.println("Store deleted");
               RecordStore.deleteRecordStore( "PLAYERSTORE" );
          catch( RecordStoreNotFoundException e )
               System.out.println("Exception: "+e);
          catch( RecordStoreException e )
               System.out.println("Exception: "+e);
At first i thought it might be because i hadnt closed the record store after using it in previous methods, unfortunatelly this was not the case.
Please help

Still no joy with deleting the record
I think this is what you are looking for (StackTrace)...
java.lang.NullPointerException
     at CourseListing.deleteRecord(+35)
     at CourseListing.commandAction(+49)
     at javax.microedition.lcdui.Display$DisplayAccessor.commandAction(+282)
     at javax.microedition.lcdui.Display$DisplayManagerImpl.commandAction(+10)
     at com.sun.midp.lcdui.DefaultEventHandler.commandEvent(+68)
     at com.sun.midp.lcdui.AutomatedEventHandler.commandEvent(+47)
     at com.sun.midp.lcdui.DefaultEventHandler$QueuedEventHandler.run(+250)
This is what is displayed when I try and delete a record
I have posted the whole code listing bellow the "bold" code is the code that deletes a record
