conver-ly using frecobaldi 3.0.1

[MING TSANG]

Hi, all
At frecobaldi I try to do convert-ly and it seems not working....
Three steps taken:1. I run the LSR=619 with lily v2.18 -- it works 2. I change 
version to 2.19.83 and run and I gor the following error        
Starting lilypond-windows.exe 2.19.83 [Untitled (5)]...

Exited with return code 1.

3. THEN I try to use frecobaldi v3.0.1 to do convert-ly and it is not working.  
           I select "tools" -> "updates with convert-ly..."             it did 
nothing. I then hit Run Again" and nothing happened.


How to set up frecobaladi v3.0.1 so that the tools - convert-ly works?
Thanks,Ming
