Now the problem is that it takes almost one day to download the wallet while filesize is up to 98 MB. For some reasons, their servers don't let me to download it with normal internet speed and limit my download speed significantly.
I just downloaded it now and it took roughly 20 minutes to download with my personal internet connection. I do not think it is their server limiting your download speed and surely not intentionally. Could be an overload on available connections or some other reason.
