Hello,
I made a few fixes for the python errors mentioned here and also packaged a new release zip (1.0.9) per OS.
Didnt recompile the binary since there are only python changes now. So if the binary reports still 1.0.8 as version, this is fine… (didnt bump its internal version), but the addon should be 1.0.9 now
Regarding the force fields, they should work, just tested here with force, wind and vortex and molecular. The simulation did definetely respond to the force fields.
Regarding the binary not being found, make sure to install the proper release zip for your OS. It should contain the binary (which is not inside the github source repo, but its sources are there under “source”)
Edit: I also have 64 bits versions only (precompiled)
Edit 2: seems to work 
Remarks:
- only in cycles
- only in rendered viewport and render
- need to re-bake the sim for UVs after loading (not persistent, it seems)

Edit 3: same blend, but with 30x30x30 particle grid:
