Yay, hey hey! That works! The 12.6 files were the problem. Thank you SO much! smile

This morning I opened Waves Central to see if there was anything to do there, but nothing regarding different versions of Abbey Road. I ran the Repair function (which re-installs all the Waves plugins), but the problem remained.

I should also note that REAPER shows two entries each for Abbey Road, so I'll forward this on to Waves' tech folks and see if they have anything to say.

Thank you again Blake for helping me to resolve this.
