HelpHow can I make a Proxy only client in the newest version?

I followed the instructions of the post from toddddd that showed how to add proxy to your client but it seems that it's outdated because it doesn't seem to work for me. When I start the swf after editing it, it won't open.

Did you make sure to correct the values that got censored by the forum? If you look at the comments on that post you will know what im talking about. Basically anywhere that you see "***************" needs to be corrected. The replies in the thread talk about what it needs to be corrected to.
