I am having the same problem. Before I upgraded to 4.12.6 Pro I could download at up to 125 KB/s. Now I am lucky to get 1 or 2 KB/s. I have tested my connection download speed, and depending on which site I use to do the test, I have anywhere from 1250 to 4000 kbps download speed. I have a wireless high speed connection, I am using Win XP, no firewall, Java 1.5. Nothing has changed on my PC from before, yet now my download speed is REAL SLOW. Can anyone HELP. PLEASE.
