how i can chenge tracker for upload? i want to change https tracker to http

You can't directly, but you can add the http tracker and then disable the https.

no, it's private torrent. maybe i mist change some files in torX directories?

3.3beta1 allows you to add trackers to private torrents.

There is also option to manually edit the announce list in the torrent, but that's tricky, if you don't know the actual format.
