If you have forgotten your LaRPS PIN Code, go to the Second Life Role Playing area's hub where you got your LaRPS System from, and locate the box that says "FORGOT PINCODE".
If you can't find the PINCODE box near the LaRPS vendor at the hub, there are PINCODE terminals at Vamporium and Isle of Legacies.
Just click on the PINCODE terminal and follow the directions.
If you still can't find the PINCODE, please request a new PINCODE from TriJin Bade
