The plugin is using the latest Adobe After Effects SDK(22.0.0) to allow for multi-frame rendering which seems to sometimes break the much older versions of After Effects (CS6 11.0.2) in some ways.
I've found some opportunities to handle suite acquisition a little better so it is resilient to handling missing suites. Try the latest upload and let me know how it goes! I'd much rather maintain a singular executable that works on each version than maintain multiple different uploaded versions.
