Career save completely broken

[Echa]

I recently decided to start up a new career mode with some new mods. After messing around in one of my sandbox games for a few days, I went back to the career game. When I entered the R&D building to unlock some stuff, I couldn't exit back to the space center. The mods/contracts toolbar pops up under the exit button (top right) when I click it. The exit button that is normally there when you're on the space center screen (bottom right) also appears. I can click on it[bottom right button] but if I click on "quit to main menu" nothing happens. The game will not go back to the space center nor will it let me exit the save entirely and choose a different game to load.

This only happens on that career save; my sandbox game works perfectly fine.

The most recent mods I've installed are USI's MKS/OKS and ART as well as SCANsat. SCANsat was the most recent addition - I removed it and there was no change in the game's behavior.

Mods installed:

MKS/OKS + community resource pack

Asteroid Recycling Technologies (ART)

Environment enhancement/distant object enhancement

Kerbal Engineer

Kerbal Alarm clock

KAS

KW Rocketry

TAC life support & fuel balancer

Probably more that I forgot to list. Mod folder: http://imgur.com/Ta91Snb

In case its useful in some way:

I'm running Win7 Home Premium x64,

i7 920 @2.67GHz

12GB RAM (I think its at 1333MHz)

Nvidia GTX 570

Zonealarm AV/Firewall

A few screenshots of the R&D building with the extra buttons over the top of the exit button:

--I wrote the above before doing some additional testing. It appears that I can only enter the R&D, admin, mission control, and astronaut complex buildings. The VAH, SPH, and tracking station do nothing when I click on them. The runway and launchpad only allow me to launch vessels that I built (no stock ships are available - though that may be because I don't have enough parts unlocked yet). I cannot select any ships to launch on the launch pad and hitting the "edit" button crashes the game. The R&D, administration, and mission control buildings all share the same behavior described in the top paragraph. The astronaut complex will allow me to exit but freezes the game upon going back to the space center. After leaving the astronaut complex, I cannot click on any building in the space center.

Please read the How to Get Support sticky. It's hard to provide support without good information about possible causes, not just the symptoms.

The only possible cause I see is that you've installed KAC incorrectly, but I've never seen it cause these issues before.

Okay, as a linux fanboy, here are your options for more stability or less crashes and stuff.

First option: Switch to 32 bit Windows KSP, and use less mods.

Second option: LINUX!

Linux 64bit is still experimental, but works much, MUCH better and much faster.

I can run PlanetFactory with Urania and Sentar, plus maybe 14 (I think) other mods, like B9, LLL and others.

So yeah, keep in mind that Linux is a good option

I use Kubuntu, that seems to be good for KSP.
