Nios II IDE programming issue

Hi,

I'm attempting to build a simple Nios II system on a DE2 board. I've followed the "Nios II Hardware Development Tutorial", but am having a problem downloading the compiled software to the processor. I've implemented a SOPC with a Nios II/e, 64K of onchip RAM, JTAG USB, and several PIO inputs and outputs. The system generates fine, I instantiate the processor in my main Verilog program, compiles fine, then download the SRAM chain using JTAG. My Nios program compiles fine, but when attempting to Run, I see the program interface with the DE2 (Load LED activates and deactivates), but I receive the following error message.

-------------------------------------------

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Pausing target processor: not responding.

Resetting and trying again: FAILED

Leaving target processor paused

-------------------------------------------

Searching for the following error message in the NIOS IDE tells me there was a problem in older versions of Quartus, but should be resolved. I'm using Quartus II v9.0sp2 and Nios II IDE9.0 build 132 on WinXP (up to date).

Any help would be appreciated.

Thanks,

Jason
