Swept Cut operation failure???

i am trying to sweep cut a profile as seen in the attached model but the swept cut feature will not allow it.  I have done the exact same operation in 2012 and it worked without issue (same sketch, helix, dimensions) so I'm not sure what's going on.

Can someone open the model and try to sweep cut sketch11 along the helix and tell me if it works?

Thanks,

Ryan
