Distiller 8 problem with Intel Mac?

I just upgraded my desktop Mac in order to install CS3. I'm already running CS3 on a G4PB with no problems. Aside from the Intel/PPC difference, both computers have the same setups and files, both currently running OSX.4.11. (The new computer was set up by migrating setups from the old computer via firewire, then CS3 was installed.)

On the new computer, when I try to distill a file with Distiller 8, the file doesn't process (error message below). The same file processes OK with Distiller 7 on the new computer, also with Distiller 8 on the G4PB. The results are the same whether I'm using prebuilt or custom Distiller settings.

With Distiller 7:

Any suggestions other than keeping CS2 on the desktop Mac?
