LOLZ Unpacking problem

[biotec2k8]

Unfortunately, unpacking my xxx.bin, which was packed with Arc and Srep + LOLZ, does not work.

I use Tiny-Toolz as a GUI.

The entries for LOLZ in the Arc.ini are:

[External compressor:lolz]

header = 0
packcmd = "lz\lolz_x64.exe" -mt4 -mc256 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = "lz\lolz_x64.exe" -mt4 -mc256 $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

[External compressor:lolzi]

header = 0
packcmd = "lz\lolz2_x64.exe" {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = "lz\lolz2_x64.exe" {options} $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

I have now created a file with the name as specified, but unfortunately Unarc does not unzip my bin. A directory is created in the unpacking directory, but it is empty.

There's a bug somewhere. But which one.
