problem with batch torrents

I'm downloading Naruto 51-60 (batch torrent) using ABC (also tried Shadow - the same situation).
The whole progress is about 41%
in torrent details:
naruto 51 - 97%
naruto 52 - 56%
naruto 53 - 46%
...
naruto 59 - 42%
naruto 60 - 30%

i checked filesizes in explorer
naruto 51 - 171mb
naruto 52 - 176mb
naruto 53 - 173mb
...
naruto 59 - 0mb
naruto 60 - 0mb

then i tried to download naruto 52 separately (using the avi file from batch download) and ABC said that there are only 34% dowloaded although in batch there were 56%.

Can anybody explain me this situation? Does the batch download work correctly? Can I finish a single file from batch separately without losing the data?

never close with X, always use cancel, else your bt data wont save properly

Ok, but in this case BT client will find all errors during checking. The problem is that BT display wrong information about the downloaded files. Any way thank you for information.
