Window Freeze 5 Boxing

Hello new here and new using ISB for EQ. I've been loading 5 accounts trying to set up ISB and each character. Randomly when I click to broadcast it freezes the game. Only one freezes. The other 4 continue to function properly. I uploaded a compatibility at paste isboxer not sure if I did it right or have to share a link.
