Problem

I installed the package (v2 fixed) for the Repeatable Data Type. I created a data type for an image gallery with a media picker and a caption (textstring). I then added the item to my Document Type (which was working perfectly before this) and in the backend editing interface I receive this fun error. I went back and removed the media picker and textstring from the Repeater control and didn't receive the error. Of course at that point I have an empty and not so useful repeater. Do I need to do something additional to setup the repeater package for use?
