Oligarc AU not validating in Logic 8 / Snow Leopard

Just downloaded and purchased the latest oligarc version but the Audio Unit Manger in Logic Pro 8 (running on snow Leopard) is telling me the AU are failing to validate. Tried various suggestions on other threads in terms of downloading and uncompressing the .zip using the built-in Apple tools and this hasn’t worked.

Interestingly, I downloaded the Spectro beta from one of your other threads and this AU did validate.

Is this a known issue? If so, when do you expect a resolution?

Thx
