need help fixing, space shuttle engines only mod

[jake9039]

I have a space shuttle that should work, but it doesn't for some reason. all things line up, do a runway test of just the orbiter; BOOM! it falls apart. think"oh, it should be fixed by everything else in the vab. do a test launch, BOom! all falls apart. why? is it my complex wing geometry tht overlaps and seems weird? is it the mod? is it how heavy? if I have the engines off during launch it's ok. what is going on?!?!?

I will put down some pictures soon, but need help with it. it just falls apart. the engines are put on low thrust limiter for now

edit: I just loaded it up to show, now it works fine exept the fact that the engines are too much

another edit: it falls apart again now
