"New Game" Start Problems

I'm experiencing an issue that I haven't seen anywhere else on the site (I tried the search function as well as just scrolling through "Morroblivion Problems" in hopes of seeing something familiar). I'm pretty new to modding, so I'm guessing that I have something installed incorrectly. I've already uninstalled and reinstalled everything once, though, so I'm out of ideas.

Oblivion starts up fine, but when I get to the main menu screen and click either "new game" or "load game" the text vanishes, leaving only the scrolling map menu background. I have Better Cities installed, the Better Cities in-game menu appears as normal, but when I close it I'm left with just the map screen. The game doesn't start. It looks like this: 

I get the "mundus has shifted" message as well as a couple others I'm pretty sure aren't related to the problem (like the one shown above). The game doesn't crash, just stays on this screen until I exit the game. Here's my load order: 

Any ideas? Thanks.

Edit: I should note that my first installation attempt was several months ago. I didn't have Better Cities installed then but I was experiencing the same problem.
