Just thought I’d drop a note in here to say that I got in touch with Seamus Leahy and he updated his plugin to be compatible with ACF 4.

He also pointed me in the direction of an alternative. I haven’t used this, but just passing along the information for anyone else who may run across this issue in the future.
