This error is very common, one thing could be the reset_n of the processor, check if this signal is connected to VCC. If this doesn't work, try connectting the module Reset_delay to Reset_n from one of the examples shipped with the board. That work for me.

See the DE2_70_NIOS_HOST_MOUSE_VGA example, there it's the connection of reset_n to reset delay.  

 A question: NIOS II IDE works with other examples like the one mentioned above? Just to make sure the NIOS II IDE is working.

The tutorial comes with the DE-70 board kit is not correct, the tutorial is old version for DE2-60 board. So as long as I followed the tutorial I will get wrong result and problem.

Glad you made it, could u mention what was the problem so I know in case happens the same to me in some other time?

Because the tutorial with incorrect the pin name variable, so we have to change it to correct one. For example, CLOCK_50 signal in tutorial should be iCLK_50, and so one. You could look at the DE2_70_pin assignment file, and you will find the correct pin name. FYI the user manual also wrong with the pin name
