The problem is that jigdo create about a 4.2 Gb iso.tmp file and after exit. After I can start jigdo-lite again but don't change anything... If I rename the iso.tmp to .iso I can view with windows commander.Virtually all files are in this iso, but failed, and it is impossible that I can download more than 4 Gb less than 10 minute with a 512 DSL connection...
