Launcherv2.java:103: showOptionDialog(java.awt.Component,java.lang.Obje ct,java.l
ang.String,int,int,javax.swing.Icon,java.lang.Obje ct[],java.lang.Object) in java

int download = JOptionPane.showOptionDialog("Wou
ld you like to update/download?",JOptionPane.YES_NO_OPTION);
^

2 errors

Your problem is with a single JOptionPane method call and you post a couple of hundred lines of network communication stuff, including absurd amounts of vertical whitespace? I nearly didn't bother to even take a look.

Anyways. Do you know how to find and read an API? Have you checked the API for JOptionPane#showOptionDialog? Do you see any overload that takes two parameters?

Sorry, but I use the the whitespace to separate areas of code, which is what I incorrectly thought everyone else did, thanks for the help, I'll check it out. Sorry for asking but what do you mean by

overload that takes two parameters

?

EDIT:
Also how do I edit the original post, there isn't an 'edit' button like for this one

/EDIT

EDIT2:
cool sig

OK let's take it one thing at a time.

Do you know where to find the API for JOptionPane?

As for acceptable amounts of vertical whitespace and other formatting niceties, I recommend you go through Code Conventions for the Java(TM) Programming Language: Contents

Sorry, I realise now that there is no need for such meaningless confusing amounts of whitespace, and have just read the whitespace code conventions page. Any future help that I ask for will be properly whitespaced. Also, what do you mean by

the API for JOptionPane

unless you mean javax.swing.JOptionPane , I used the * wildcard, because I thought the error was coming from a misspelling or something like that. Thanks for your help, I'm a noob/newbie at java so I don't know that much. And how do I edit the original post to get rid of the whitespace? Thanks
