Reboot your router, delete your cookies then log again. If you have an ISP with Dynamic IP, it's the safest way
Yes, try this way: . Type cmd then press Ok . Type ipconfig to see the IP you have . Type ipconfig /release to let go of the address. . Type ipconfig /renew to obtain a new IP address This works *only* with a USB/Ethernet modem, not with routers
It depends upon if its a static of dynamic IP address. You might actually have to call up your ISP and request a new IP or just proxy.
Call your ISP and ask if you have a Dynamic or Static IP In case of Static, you have to use Proxies --> http://en.wikipedia.org/wiki/Proxy_server
