Hello all. Although this didn't get a response, I managed to fix it and wanted to report the findings in case anyone else has this problem.
If you experience crashes on embark, follow these steps:
1. Back up your saves. You are probably going to lose them, but they might work.
2. Delete your masterwork install and all files associated.
3. Go into %appdata% (windows + r), go into the Local file, and delete the Meph Team directory found there.
4. Create a fresh install of masterwork. Put this file into C: drive on your computer, or whatever your main hard drive is. Not Desktop.
5. When embarking, resize the game window, not embark size, to small before entering the prepare screen.
6. Wait 10 to 20 seconds before pressing enter on the embark blurb screen.
7. Play freely! Works every time, no script problems here on out.
Hope this helps anyone else who gets stuck.
