Uisng NIOS II on DE2

I am I am using DE2 and Quartus 8.0 web edition

I started with the tutorial (Introduction to the Altera SOPC Builder Using

Verilog Design) generated the processor, and compiled my code without a problem. Starting the programmer, I get

"you are trying to use one or more time-limited megafunctions that supports the opencore plus feature that will not work after the hardware evaluation time expires. Refer to the evaluation window for evaluation time details" I press O.K.

Then when I download the file lights_time_limited.sof

I get a window "opencore plus status" saying "click cancel to stop using opencoreplus Ip

Time remaining unlimited." clicking cancel (the only choice)

In the message window, I get configuration succeeded one device configured. successfully performed operation and ended programmer operation.

Now I use the altera monitor program to compile and download the example, compilation is O.K. but downloading I get

using Cable "USB-Blaster [USB-0]" device 1, instance 0x00

Resetting and pausing target processor: FAILED

leaving target processor paused.

I tried more than one board, reset is connected to KEY[0], clock is connected ... same results.
