Transmission showing created files as incomplete

[charliechan]

So I created a .torrent using utorrent on WinXP and seeded for a while.

I decided to move everything over to Ubuntu (latest version) and seed with transmission. I downloaded the .torrent from the tracker, it checked the folder I'd moved, and now says I only have 99% of one of the files. And of course there's no one else seeding this. I don't quite understand, since all the files and everything are originals, and it was the same .torrent file I'd used in utorrent.

Are there any workarounds so it looks like I'm seeding and not leeching?
