Are you on wireless or LAN? Do you have access to your modem to set yourself as the DMZ?

Also, I know you're fed up, but if you want actual tech support, I would change the title of your thread to something that includes the actual issue you are experiencing. Like, "Had enough - Patch will not download, gives errors" so that if someone from SE tech support is looking into these threads, they have an idea of what the issue is going to be about.

That's advice that applies in all situations for tech support. We know you're upset. We need to know why if you want us to fix it.
