Dynamic Link Error (trying to render the Comp)

Using Premiere Pro CC and After Effects CC:

AE won't let me render a lossless video from a comp I created using Dynamic Link inside Premiere.  The workflow I'm currently trying to use is to lay out all my clips in Premiere, dynamic link to AE for denoise, grading, sharpening, add grain, stabilize, etc, render a lossless clip in AE, and then replace the dynamic link comp in the Premier timeline.  Unfortunately I get an error everytime I try to render my Comp from AE.  It will render a single frame using "Save Frame As" but it errors out with a sequence (.avi, .mov, and I even tried a targa sequence).

I'm running a Windows 7 64 bit workstation.
