I'm pretty sure that's because only Premium Members can. For those who can't it states that free mirrors will be split up into multiple parts that all need to be downloaded. And because of the slow download it's taking me 45 minutes to an hour for each part. So this is going to take a good day to download, with all the one file at a time, 20 minute after each one has downloaded. etc. etc.
I can't find the config file for the first eight folders that I've just downloaded. Each of the updates seems to have it's own config file included in the folder, but I can't located one for the original megapack. I'd appreciate some help in locating in please!
