Jbl calculator for iPad crashes when launched

I just installed the JBL Vertec Line Array Calculator for subwoofer modelling on my iPad. The application just crashes when launched. I need help with JBL calculator for iPad. I have the 64 GB iPad 2 that has the Apple A5 chipset, Dual-core 1 GHz Cortex-A9 CPU, PowerVR SGX543MP2 GPU and iOS 4. Do I have to update the latest version of OSx for this to work?
