1.Delete the cookies in your browser(internet explorer or firefox or opera or whatever u use).
2.Press start->run,type cmd.
3.In the command prompt,type ipconfig/flushdns press enter.Then type ipconfig/release,then ipconfig/renew .Now type exit.
4.Now try downloading,for many people this may work if their ISP provides a dynamic ip.
Method 2
1.Just switch off your router(or modem) and switch it back on.
2.This may work for some users(Mtnl and Bsnl) and maybe some others too.
Actually these methods generally work for those people whose ISP gives them dynamic ip.
If these dont work then one more thing that can be done is to use proxies.
when i type ipconfig/release in cmd. It shows the message"error occured when releasing adapter Local Area Connection : Connection failure or insufficient access"
Maybe I was doing something wrong, but i've tried that and it only works one time. I couldn't get it to work properly after that. Anyone got any suggestions as to what I may have been doing wrong?
