There is 2 errors srep decompression problem and the second one is that your system doesn't have enough ram
This is how srep conifguration should look like in arc.ini and it's working good for me if srep64 gave decompression error try removing -s parameter :

[External compressor:srep]
;options = l%d (minimal match length, default=512)
header = 0
mem = 1024
packcmd = srep {options} -a1 -m5f $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep -d $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

[External compressor:srep64]
header = 0
mem = 1024
packcmd = srep64 -m3f -d1g -a2 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep64 -d -s $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
