my aunt let me borrow her guitar, i desparately need this for i have no amp in here. here's what I did.

open guitar rig 4 -> guitar -> cable -> 1/8 adaptor -> mic-in

here's my laptop if its any help. http://www.villman.com/Product-Detail/Compaq_CQ35-110TU

I can't find the line-in. And I don't know if I have to change settings or something. I'm pretty stupid at this.
