Ascent Guidance help?

[Radon86 95]

So i said this before and i'm sure someone has asked this at least once, that i installed the latest MechJeb (for 1.0.2) and i turned on Ascent Guidance.And suddenly my rocket flipped out of control and splashed into the ocean not even 20 km from the KSC.My question is, how do i make Ascent Guidance work with the new aerodynamics?

BTW, i know it's not a bug or anything like that, i am just looking for a solution.

If you are trying to get something into orbit using MechJeb, my best advise is not to activate it until 28km-30km. I have been putting up heavy equipment for an orbital space station and its so lopsided that my ship will spin out of control if I let Mechjeb create my orbit before 28km : p It is entertaining the first time, but after that I always make sure I have enough reaction wheels so my ship can control itself and I don't pres that autopilot button until I'm up high enough with enough velocity to have control maneuvers. Hope that helps! Happy flying.
