APP is the only software I know which can give you this interesting zig zag pattern, I like it but that doesn't solve your problem.
There can be several issues why APP is not stitching it properly.
Do you have exif information in the images or is it missing? APP needs that, if you have it then try setting the following settings for detection.
Quality of detection set to "high"
check "Force every image to be in the same panorama"
This should work & you may want to read these threads dealing with somewhat similar problems.http://www.autopano.net/forum/t5053-app-is-overlapping-similar-photos-on-inside-of-buildinghttp://www.autopano.net/forum/t4989-need-support-to-make-zenith-and-nadir-look-right-in-app
If you still cant get that stitched post your images downsized with exif info intact & members will be happy to help you by stitching your images & tell you whats going wrong & how to deal with it. Also post your shooting setup, eg lens/camera/panohead & other relevant details.
