Hi @jeremy5,
There was an enhancement added to odrive1 recently (Desktop Release (05-17-2018) Win v.6317 / Mac v.6386) that does a final check on the file being downloaded to ensure that it is the same size as the remote storage is reporting. If it is not the same size then you will see this error.
Are you seeing this for many files, or is it this specific file type, or just this one file?
—Edit for people that may come to this thread after seeing this error—
We added the ability to disable this check, if required. See this post for more details:
