ESX. Real Instruments in GB disappeared after Lion Upgrade

Hi:

After upgrading to Lion and Moutain Lion all of our 3rd party real instruments have disappeared in Garageband. They worked perfectly fine before the upgrade. I have tried re-installing, etc. And nothing. They are located in the appropriate folders in library/applications support/Garageband/iinstrument library, etc.

The still work in Logic, but have disappeared in Garageband.

Any ideas?
