I'm not sure if you guys already know this but I'll post it just in case. This works if you have a speedstream DSL modem and bell sympatico as you ISP. Download Belarc Adviser (
http://www.belarc.com/free_download.html) and install and run it. When you run it it will show a profile of your computer. On the right side Under the "Comunications" heading there will be a line saying Networking DNS sever. Copy that number into your browser. A screen with some info will come up. Push the disconnect button (making sure there is not activity i.e. downloading). It will then say connect, so push it again. This will change your IP and make you unnoticible to rapidshare as it doesn't use cookies. This is how I always download multi-part files faster. If you have something else liek rogers download an IP changer software from somewhere else and it should also work
NOTE: Do not Disconnect-Reconnet to fast or your IP will not change and may crash the control panel itself.
Hope this is helpful.
