WinDebug says:  Access violation - code c0000005

So it's a classic access violation (or General Protection Fault)

Something (=KSP) tried to access memory at an address it wasn't allowed to access.

Doh... one of the most common and hard-to-track errors :( 

Long story short, one of the most common causes for that crappy message is something being wrong with your Windows profile (other reasons: something is wrong with your Windows installation, software, and a 1000 other reasons)

To check: try making a new user account and start KSP from that.

If that helps: profile problem

If not: further investigation required

Ideally one would have the so called symbols for the exe and any dll's, then the debugger can tell you what caused that access violation. Such analysis though costs a lot of time and quite often leads to no practical usable results. In your case, WinDebug gave me:

Not easy to understand, if you're not a programmer... and I'm just a simple administrator myself, knowing only the very basics about debugging ;) 

What I can see here is that a function call NtGetContextThread to the ntdll.dll failed, the ntdll.dll is a core Windows library and is 99+% not to blame, usually this is caused by either a bad user profile, or bad drivers (graphics driver are most common here), or a bad application module.

Go figure... yeah, this stuff sucks :D
