If you are using an FTP client to transfer your package data to a server to later feed through the TT package system and downloader, make sure you upload the files in explicit "binary" mode rather than allowing the FTP client to upload text files in "text" mode.
There have been a few problems where files uploaded in "text" mode have their line endings changed which breaks the package system/downloader.
How you do this depends on the specific FTP client.
