Look on the alterIWnet website, there is a xfire unlocker there.
I'll download and upload here
Please allow 1 scan, I hope I wont have to upload 2 virus scans when I just post it in here. (Not as a thread..) I've got this directly from the alterIWnet scan. Mods can try this file before they approve it. It has no virus..
These will make xfire work for alterIWnet. Enjoy dude!
