There’s an issue with the latest R14 update and Render Elements. It is related to some stuff apple did that affected some builds of C4D. I am aware of the problem and will do my best to fix it within the next few weeks. Should just be a re-compile, but my understanding is that there is some additional setup work that needs to be done with the new version of C4D. Boring technical details, blah, blah, blah. Will update when I have progress to report.
**UPDATE**
Should be fixed, here: https://adamswaab.wordpress.com/2012/10/16/render-elements-v0-7-15-r14-only/
