Patches and discussion for Ensoniq VFX family

Guys/Gals,

I've been experiencing some problems with my SOUNDLIB program (namely,
that since a failed install of Windows XP SP2 it has caused access
faults and won't open, no matter how many attempts to re-install
it...grr...), and in a search for another option to transfer patches
from the comp to the keys, I came across jsynthlib, a JAVA-based
librarian/editor.  It appears to be fully functional with the VFX (in
library capacity only...have to blow the money on MidiQuest to get a
pc-based patch editor, I guess!), and has already successfully
accepted a sysex dump from the vanilla VFX, but it's still not
auditioning/playing patches on-demand.  

My question is, I guess, have any of you used this program with your
VFX (mine's vanilla, but I don't think that matters) with positive
results?       
Failing that, does anyone have any advice about the soundlib problems?
 VFXLib causes the same problem, so that's a no-go.  

If it helps...

Vanilla VFX --> M-Audio Uno USB MIDI port --> DELL Dimension w/ 256 MB RAM

Lemme know what you think, I'm at a loss, and I'd really like to get
my old patches back on the system.  

Best,
justin
