I've had similar problems, eventually got it running but it crashed consistently after a few minutes.
It's not a full replacement, but I've created a mids build reader over the past week to at least be able to pull up your mids builds and see them from a browser:

Planning to add some features to it to render builds better, detect rule of 5 violations, etc - but for now, you can upload a .mxd file and see your build.
