DX Driver is the wrong version

I am hoping someone can help me here.  Avid tech support was no help.

I installed Avid Symphony 6.5 on a system that previously had Avid 6.0.3 on it.  I did this only because I needed some colour correction tools with Symphony.  I uninstalled MC 6.0.3 and installed 6.5.

It did a firmware update on my Mojo DX box.  When I was done with 6.5, I uninstalled it and put my MC 6.0.3 back on.

It now says that the DX version is 5.9 but require 5.7 to work.

I went on the Avid site and downloade a back revision firmware.  I ran that and it did not work.

Now I have a dead Avid because of this firmware update.  Can anyone please help me?

Thanks in advance.
