Adjusting the horizonral plane/horizon

Hi all

I have shot a (interior) room twice now and while my tripod and head were not 'perfect' they were pretty good... in my previous softwear there was some *intellegent* correction, but with the easypano my output is VERY wave like swigning out of horizontal alighnmet by about 20˚...

Can i adjust this post shoot, I'm sure i wans't that far out on setting the tripod!

Perhaps there a setting to manually align the panoramic?

i would like to find ou the answerr to this question too if possible. Ive double checked my settings on the camera/triod but i still have thi issue on it.
