Upgrading from 7.06 to 9.62

I am in the process of moving from Dynamic C 7.06 to 9.62, most of my programs running on the RCM2120 compile and run fine. When running a larger program requiring the use 2nd flash, the debugger times-out at the XPC pointer to main() function. Are there any hints to where I may be going wrong?

What is the exact error message?
