Only 1 instance of WOW loads

I have Win7 64Bit
When i try to load a group using innerspace, only one instance of WOW loads. and when I enter into the game to play just the one instance with IS running my mouse just goes crazy, The world just spins. Please help

Make sure WoW is in Direct3D9 mode (Inner Space does not currently support Direct3D11, but support should be coming soon), and that Hardware Cursor is enabled
