Using niosII IDE about ecos

Hi:

I followed the steps on the "ecos for niosII " offered by ecos , and now I was up to the step 7th : using niosII IDE , when I fixed all of the design, and using the "niosII Instruction Set Simulator " to "debug..." the "hello" ,and found the following errors:

who can tell me what's wrong with it ? and how can I do for it ?

help!!!!!
