Well.
Did you tried to download the files from outside the EU? respectivly from "oversea"? When did you tried? We have the most traffic, and, as well, the most Problems between 18p.m. and 1a.m., so maybe try it in the morning or the early afternoon?
Did all packs fail or just one?
For all I can say: The files are ok, the download works fine every time I try it. So I can not really change anything. Maybe it get better if we upgrade to a better/bigger server, but we recieve way to less donations to pay a bigger Server. In fact it is barely enough to cover our costs with the small version.
