In the meantime I was able to download all segments. The issue is a quite easy one which can be solved be trying and trying again .
Technically, both of my different DSL lines in my house and appartment in another city are provided by Deutsche Telekom. Sometimes (or manytimes), the DSL line drops for a moment - what you never realize when you simply surf the net - and the download agents are immediately trying to recover the connection. That is not possible with the LL Store, because the link to the file is valid for a short period only. Therefore, I must have luck to get no DSL line drops for an hour, what is the typical time to download a segment.
Not the best solution, I think.
Michael, is there a chance, that the download links stay longer, e.g. 90 minutes, to ensure a complete download?
