Hi, I'm from Japan and also I have the same problem.
In my case, I tried to DL Vienna Ensemble 7 (ver 7.3.3388) any number of times via Vienna Assistant (of course the newest version) and always got network error (roughly it always stops at about 80% to 90%) in the end.
Can you send me a link to download it for sure?
And I have the other question; Is it possible to download from the continuation of the disconnect, or if not currently possible, could you update the application so that it can be done in the future?
I think many applications from other companies (not just music content) seem to be able to do this.
If this could be done, I think it would further improve the usability of the application.
I also love and use VSL's content, so it would be great if you would consider this.
Regards
