Did you try with out differential encoding? I didn't see anything in the Constellation Receiver saying it handles decoding...

I am trying to replace the QAM mod/demod blocks with constellation mod/recvr blocks in my flowgraph.
With QAM mod/demod, the first few and last few bytes of the output file are junk.
With const. mod/recvr, 100% of the output file is junk. What could I be doing wrong??
