VIRTUAL GUITARIST 2 get it to work SNOW LEOPARD 10.6.x

hey guys,
VG2 works great in logic 9.1.3 oxs 10.6.7 on my macbook pro 2010 2.4ghz. BUT it doesn’t work on exactly the same system (cloned) and macbook pro 2011 i7. i wonder if it could be hardware issue? or what should i look for to get it working on my macbook pro 2011.
