PhoeniX WorX :: Community

My best friend plays TA also, well before I joined PhoeniX WorX, we tried to play on GameSpy Arcade, it wouldn't work (Battle.net is so much cooler than GSA!!!!!).  Well then we tried to find out a new way to play.  I got PhoeniX WorX.  I told him about it, he said he couldn't install it.  Anyone know how to fix his problem?
