linefind searches only for vertical line. Either the orientation of your 
images does not match (wrong rotation information) or you rotated the 
images in Hugin.
If you don't provide more information, it is impossible to fix it.

Using horizontal and vertical lines to rectify an image works only for 
rectilinear projection. In all other projections this make more trouble 
than it helps, so it is not independently form the projection.

This is possible, but not on the assistant tab. Use the stitcher tab.
