I have the same problem, I updated my Mpc from 3.5x.xxx.x to 3.70.885.0 and it hangs when it start up, at the "starting 2D plan" after a while, a popup occurs title : "Martin Mx Controller"
Message : "Martin Mx controller has stopped working""Windows is checking for a solution to the problem..."
I've tried to uninstall with the special removal tool, of martin, no change.
My pc specs
Windows 7 32bit
