Avid MC 8.3 gives me a "Wrong Format" error when AMA linking A7s Mp4 footage

--- Update 1/25/2015 ---

All right, as of Jan 30, 2015 there is now a (SUPPOSEDLY) MC 8.3 compatible Plug-in which is PDZK-MA2_v3.40, available here: http://www.sonycreativesoftware.com/download/pdzk-ma2

But first, uninstall the old v3.32, on Mac: 
1) Navigate to <SYSTEM DRIVE>/Library/Application Support/Avid/AVX2_Plug-ins/AMA/
2) Delete the MVP_SonyXDCAMEX.avx and SonyXDCAM.avx files
3) Empty the Trash to completely erase the files from the system.

Then Install v3.40.

In MC's Console ama_listplugins it shows the following:
MVP_MSP_SonyXDCAMEX_64bit Sony Corporation 1.9001
SonyXDCAM_64bit Sony Corporation 3.4000.0.381

And... IT STILL DOES NOT WORK, STILL GIVES THE WRONG FORMAT!

In Console, I get the following:

------ AMA Link To File(s) ------

The video track contains non-trivial edit list(s).Forcing sample provider mode for video.

Color transfer characteristics information unavailable

Color primaries information unavailable

And If I select the accompanying XML file to the MP4. I get an error message:
Unable to link to file or volume.
You may need to Download & install the AMA plug-in from the Avid AMA website.

Great!  What a great compatibility!  I'm not the only one.

I have Sony's PDZK-MA2_v3.32 plug-in installed.

In MC's Console ama_listplugins it shows the following:

MVP_MSP_SonyXDCAMEX_64bit Sony Corporation 1.9001

SonyXDCAM_64bit Sony Corporation 3.3200.0.287

I can import the Mp4 footage, but I cannot open it.
