I've just been notified that my download limits have been reset and the download limits are 20 gb per 72 hours. I guess if you don't contact support they do not reset your limits. I don't know if they reset based on your first download or based on their servers time.
So, thats a downloadlimit of 20 gb in three days? That would even be worse than k2s with 20 in 24 hours. If so, as a downloader, filejoker doesn't look as an option to me.
