I just bought Okami HD in Russian Store, but can't download it completely.
I tried six times and it always starts downloading at maximum speed, but just around 1 Gb the download becomes very slow and eventually freezes. Pausing and resuming helps sometimes, but mostly not.
With one frozen download I am able to start another and it goes normal for the first 1 Gb, then freezes too, etc.
I have enough disc space, and my home network works ok.
