This error can happen only in DC++ 0.699 and older as from 0.700 and on resume and integrity check is done in another way.

This message means that somehow the data has become corrupted during a transfer. Usually it's because one of the users, either you or the one you are downloading from, is using a bad firewall, such as Zone Alarm, which is intercepting some packets. There are three things you can try to fix the problem:

  1. You can attempt to fix the file by chopping off the rollback bytes, using a tool like cutoff.
  2. Delete the file and re-download it.
  3. Completely disable the rollback feature by changing the value in Settings -> Advanced to 0. You can do this, but at your own risk. The rollback is a scheme to ensure that the file you're resuming and the file you're downloading from a remote source are the same. If you disable it after getting the rollback inconsistency message, there will be corruption.
