Hey Sam22,
you maybe can change your DNS to something else.
If you don't know how to do that, here it comes.
If u use LAN network:
>Go to Control Panel>Network Connections and select your local network.
Click Properties, then select Internet Protocol (TCP/IP).
Click Properties.
Then look for : Use the following DNS server adresses.
When you found that you need to put in a DNS.
I prefer google's one.
That is:
8.8.8.8
and second 8.8.4.4
Those are your 2 new DNS servers
For Wireless:
do the same but look for
Internet Protocol (TCP/IPv4)
tell me if it worked
