I’m sure this has been covered, but I’m having trouble finding the answer. I just upgraded my OS to 10.6.3 and all of my Stillwell plugins below version 2.0 will not validate in Logic 9.1.3. Please advise soon. I need these.
Thanks,
Don

The correct answer is to download the latest versions…they should work in Snow Leopard no problem. Save your existing copies “just in case”

Thanks Scott. I assume by the latest versions you mean the demo versions?

Yessir…there is no “registered version”…it’s the key file that makes the demo version registered, and we haven’t made any updates yet that would require a new key file (for example, paid upgrades)
