You have asked Modeller to read structural information from a PDB file, 
starting at residue number "A" in chain "3". Modeller's simply telling 
you it can't find that residue and chain. Most likely you actually meant 
residue "3" in chain "A" - i.e. you simply have the residue numbers and 
chain IDs the wrong way round in your alignment files.
