Its status is "Finished"? ...
Haha, just wanted to throw out there (before thread gets locked) that OP mentioned that...
I think newy answers too many "ZOMG CAN'T SEED HALP MEH" questions. At least the analogies are interesting.
now.. how can i make this post with the [solved] mark in it....
Either you figured that out yourself or a moderator did it for you... I wasn't aware you could do that.
oh COOL!
i'm seeding now.
alright. the solution is to start the torrent.
THANK! 
To avoid this issue in the future you have to change your settings, unless you enjoy hitting the start button for every finished torrent. There should be one page that sets torrent behavior upon completion. Set it to seed forever instead of stopping when you're done downloading.
