If it not your firewall nor your port number maybe it is your connection or settings. What tyoe of connection do you have? If it is dial up or ISDN it is going to be fairly slow to download files. If you have DSL or cable then that is obviously not the problem. Perhaps it the settings. Click on Tools>Options>Downloads. Then see what your bandwidth settings are. If they are not all the way up to unlimited that may be the problem.
