i've followed your advise but it hasn't work.
At the beginning program didn't show almost errors.
After first continuing project i read hts-log and saw 
few errors like: file may have been erased.But 
while second continuing, repeated files were been 
downloaded and this sort of errors already weren't 
showed in hts-log.
i erased everything except cache,hts-log and whtt.
perhaps all is due to erasing directories and not what 
was inside.
