German Pack not working.

[PanzerkommanderGER DeadbyFriday?]

I wanted to download the German Pack mod, but when I do that and it's finished it says "Paradox Mods Services could not process the request. An error occurred while writing or reading the disk." So it means mod could not be added, can someone help me PLS
