first - it can be done - thats the good answer.
but ...

if I take all 25 images of your zip file - it fails.
+ some reasons maybe: mix of focals - the nadir handheld shot does have 18mm the others 15. - i did not use the handheld nadir image with your feet (handheld + non 90" to bottom angle will in most cases not work).
+ the 15mm images are recognized as non fisheye. this maybe correct or may not. one rule: if having troubles with 15mm or smaller that are nonfisheye recognized than try it with changing in image properties to fisheye. -  I did change it to fisheye.
+ you shot with a regular image matrix - this leads to an rather big overlap in zenith row - I finally did use 5 images less... so in sum I used only 21 image to still cover the sphere.
+ you shot in landscape mode. - this may work or may not - but general practice is using portrait mode images. Advantage on indoor panos is you need less rows... and you've less ghosts from moving people (if there are ones...)
+ in screenshot you can see that autopano detected CPs between some images and between some no CPs could be detected. so I did delete all links between images not directly being neighbor images. and I manually added links between images to link the images. this dramatically reduced the detected RMS and the ceiling errors could be corrected as shown in preview mode...
+ you've dust on your lens or on your sensor. if dust is on the images (always on same x,y position) than make sure not CP's are detected by accident (didnt care about it and it worked...)

I did use apg 3.0 final. I used
Detection Quality Standard
CPs: 50 with Ransac model: Similarity
Blending settings: Multiband Level 0 with Fusion and Cutting enabled Priority to Ghost.

the screenshots:

3. mage: using nonfisheye properties and with default recognized CP connections
4. image: using with fisheye properties and after adding CPs to connect images
2. image: is the preview (preview feature with apg 3.0)
1. image: finally the resulting pano using 30% original size and 75%jpg quality compression to fit in the forum

and what with the nadir: I would use krpano tools to create cube files and postprocess the regular pattern. the corrected cube files can than remerged to a rectangular image with the kroanotools...

Liebe Gruesse,
Georg

Using a gigapan for indoorshots.....is a bit like using a pickuptruck to serve tea....if possible go manual indoor. It si then also easier to skip a few shots in the zenith.
