[External compressor:srep]
;options = l%d (minimal match length, default=512)
header = 0
packcmd = srep {options} -m3f $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep -d -s $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

check the version of srep you used to compress(Masked Data Compressor) make sure you have the right version in your script also to match the compressor.
also have you edited the blackbox script to use reflate?
