I set up a classic server, with MCForge, and it works great. People are coming on and I am even able to get on it myself with my cousins laptop. Now, on my computer, I cannot connect to ANY server at all. All I get is the error message above. Without the parentheses of course :D.

I have looked every where for an answer to this issue. 

I went through the debugging steps and got something along the lines of this in CMD:

Java.io.FileNotFoundException: http://www.minecraft.net/resources/ at sun.net.www.protocol.http.HttpURLConnection.getInputStream<Unknown Source>

at java.net.URL.openStream<Unknown Source>

It has a lot more including a 403 for a URL But its a lot to type.
