Wow - that is the exact same issue I have with MO or the NewUI's, but I can't tell why. I have been able to run both mods without issues since TDW released 6.3.7 and then one day ... lockup when I sink a ship.
I even reinstalled windows 7 (x64) again ... fresh install, bought a new version of the game (disk this time instead of DL).
Sink a ship .. win a boobie prize. ;(
