Upstore is simply terrible for free members, actually the worst I have seen so far. I think after 2-3 consecutive downloads with average speed of 75 kbps and obvious captchas - there is at least a 3-hour cool down period or possibly even longer (JDownloader says that your IP is just blocked). Also, even 74 kbps can be further reduced to about 30
.
Taking into account that movie archives are normally split into 5-7 pieces, it can take up to 12 hours to download it.
