I dled the hack. And I extracted it to the Combat Arms folder.
I put in my super secret password and usernanme (totally NOT 1234) and then I load up Combat Arms.
However, as the game is loading and I can still see my normal windows (e.g. Firefox, Microsoft Word, Google Chat, I get a window in my web browser, with the MPGH homepage and with a welcome sign "Welcome to MPGH" (with MY USERNAME ON IT!)
I have a feeling that my p/w and username aren't correctly "linking" up with the server...anybody who is somewhat l33t...any idea why it ain't workin?
