My 5 years old macbook was to slow and I bought a new macbook pro. I reinstalled my Garritan libraries running with Aria : GPO, JABB, COMB, WORLD, GIO and Steinway Basic.
The version of Aria I have is 1.111.
I activated all these libraries in the same way : saved the images to disk and dragged and dropped them onto Aria. It worked for all except the Steinway : when I drop the Steinway image, Aria says activation is OK. But when I close and restart Aria, it keeps saying that the Steinway is not activated.
