The others may be using premium (paid) accounts. Are you?
Off the top of my head, Screamer's funny NAT thing will screw up free downloading with those services (because the servers see only 1 IP for possibly hundreds of users). The reason it could have worked initially is fewer users on the service at that time.
So your work around is pay for premium accounts, or switch to another ISP that doesn't NAT. Not trying to plug their service but DigiChilli does not, though the throughput isn't exactly stunning over there atm.
