The Problem is within the Scenario you are using. You need to change the grid coordinates for the
shuttle in the Scenario file to the new location of the the launch pad. To get these numbers find a
scneario that utilizes the new Grid location. In other words find a scenario were the Shuttle is
found at the lauch pad. Open that scenario and copy the Grid coordinates to the scenario you are
using. Compare your POS in your scenario to the one below try these numbers and see what you
get.
