after using nero for a year now and only getting a 6o % success rate i've took the advice in this forum and changed to primo...now i followed charles tutorial and extracted the gi files...now in the tutorial it says file so i assume there there is only 1 file..am i correct?but i extracted 3 files and burned them all but it doesnt boot at all.am i meant to only burn 1 file ?if so which 1?they all have a .gi on the end...the game is wrc 2
