EXS 24 Logic Sampler Users Group

While trying to convert a Giga disk to EXS24 I am continually getting
the error code -insufficient access priviliges error code-5000-

This is on Quantum Leap Rare Instruments and World Winds. Other Giga
disks translate very well; Symphony of Voices- no problem.

MAC OS 10.3.5. Logic 6.42

What to do?????  thanks!
