I've attached a pic of the problem.
This is happening with every C4D file I open and drag into AE. They render and show up just find in C4D itself, but not in AE. I've tried adding lights thinking that might somehow be involved with the issue, but as you know - it didn't hep.
If anyone could offer me some assistance with this issue I'd really appreciate it. I'm just starting with C4D and of course step one is a failure...

Try following some of the tutorials linked on these pages first to get an idea of the proper workflow:
