looking for peers and doesn't start seeding

It means you are downloading your own torrent ...
Re-download the small torrent here not the torrent created by your client [it doesn't work]

For single fie point it to the folder where the file is located ...
For multiple file [pack folder] point in to the sub-directory folder where the folder located,
not on the folder you have created ...
