The only thing that I can get my xbox to connect to is Quix, and even then not really... it's reading the xbox but it won't allow me to actually DO anything.

So any attempts I have to set it up through any other FTP server such as CuteFTP or even IE fail by simply hanging there. This wasn't originally my xbox, I got it from work when it came in after realizing that it was modded, my other xbox is modded but it's a soft mod with Evox on it, not Avalaunch.

I've tried everything and I'm at my wits end about the hole thing.

Try running a different dash as your FTP server - UnleashX and XBMC both work well. You don't need to install them as the dash, just run them as an application.

And try Filezilla as your client.
