I can't enter any buildings in the Space Center and a minor bug.

[Candlelight]

I just loaded up KSP.

I have 4 mods installed: B9 Aerospace, Active Texture Managment, BDArmory and Trajectories.

I went into my sandbox save that i played not more than a week ago.

I got into the SPH and built a plane and launched it.

I turned on SAS and engines but the plane didn't move.

I disabled the brakes which i had turned on (no kidding) and it suddely spiraled out of control and exploded on the Runway.

I tried to revert the flight, but there was no "Revert to launch" or "Revert to SPH" button, just cluttered up text.

Then the game froze and i closed it, then opened the game again.

I went into the same sandbox save, but this time, i couldn't enter ANY buildings that were available in Sandbox mode. (i know that buildings such as the Administration building, Mission control etc. were locked by default in Sandbox mode).

What's even weirder is that i couldn't time warp and i couldn't go back to the main menu (well basically it froze again, and then again and again and again and i repeated the same process(close and open the game again)).

I need help, has this ever happend to you people before and did you solve it?

If so, tell me why this happens and how to solve this.
