The number of series that can be downloaded using Download Manager is dependent on several factors: average image size, RAM on your computer, free disk space on your computer, network speed, and Java limitations. If you experience issues or errors associated with the download, reduce the number of series in your basket and try again.

If you never even see the Download Manager GUI, and Java reports that the Download Manager failed to launch, you may be running an old version of Java, and/or your Java application cache may be stale and needs to be cleared.  See Clearing the Java Application Cache for instructions on how to clear the cachethe cache.

In some cases, the first attempt to run Download Manager on a computer might fail.
