Comparing that against a successful log, the very next line is it loading the House Percentage slider control for the Girl Details screen. My guess is that you're somehow missing the slider images which have been present for several versions (back to 1.30.1 at least). The slider images are in \Resources\Images\, 5 images with names starting with "Slider".
Otherwise, your Girl Details screen definition file at \Resources\Interface\girl_details_screen.xml is probably messed up.
If neither of those seems to be the case, can you try a fresh install of 1.30.4?
[EDIT]
For reference, I've personally tested installing 1.30.1 (r450), installing the 1.30.3 (r485) update, and then installing the 1.30.4 (r593) update, and it worked fine. Though, I did notice that the Intro.lua script is missing there, so you get no intro when starting a new game. That file is present in the full download of 1.30.4 (r593), though; we'll have to remember to include it in the next update for those who have taken the upgrade path rather than a fresh install of r593.
