LIEXEC export doesn't work in Draw 2.1?

Hello experts, 

I have a modified my_full_dxf.mac file with defined blocking and layering rules etc, which I run via 

LIEXEC /draft_DWG_li 'R24' ConfigData 'my_full_dxf' OUTPUTFILENAME 'C:\DUMP\myfile.dwg'

In Draw E3D 2 it seems to be entirely ignored: it runs fine; displays no errors; does not list the set of rules as in previous versions and exports a .dwg file with some (default?) settings that don't even correspond the ones set through the E3D GUI. 

If I run it in older versions (aveva 5 and E3D 1.1) the script works as it should. When I run it it displays the list of set rules

Rule 1 : SWITCH USELAYERRULES ON
Rule 2 : SWITCH LAYERDEFAA PIPING|YELLOW,CONTINUOS
Rule 3 : SWITCH PrimitiveThickness 'ON'
etc

and gives expected results in the resulting .dwg file. 

I tried adding the line
   liload /Draft_DXF_LI
before 
    dlicon /my_full_dxf

This doesn't fix the problem in 2, but errors out in older versions. 

Is there a known way to enable this for 2? My precise version id 2.1.0.32[Z21032-8]. I would prefer using scripting to GUI for batch exports and ease of transfer to other users.

Very grateful for any help!
