Pausing target processor and other problems

I added the debug core, but now also the Hello world small gives the same 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.

Then I made an own project using tut_sopc_introduction_vhdl.pdf .

It gives the same error. I set the timing constraint fmax=50 mhz. Timing report tells me the actual time is 98.89 mhz.

I connected the reset to toggle switch and tried to run the program, having the toggle switch in both positions. Again same error.

I also tried another toggle switch, again the same error.

The Quartus also tells me that i use time-limited megafunctions, although I'm using only CPU, JTAG-UART, Sysid, and two PIOs and on-chip memory.

I didn't close the "open core plus ip" dialog.
