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.

I saw that too, but the author say in the bottom of the README that the plugin is not compatible with ACF 4 yet.
