Lost a sounbank preset

[BERLY]

Hi all,
I've lost the ELECTRIC ORGAN PRESETD in the 02 Electric keyboard Soundbank of MachFive.
Even I rescan soudbank, it doesn't come back.
Even I copy it again from the M5 install CD, and rescan, I always have NO PRESET in the 02 Electri Organ sounbank...

Any idea...?

Thanks

Christophe
