Did you look at the STF fiel of the project wiht a text editor? 

 These files are plain text in a XML notation. Maybe you see something that is obviously wrong.

Thanks for your respons.  

I dont think that i have ever open an STF file with text error. there are some suggesting there must be no space character between your project path (i m referring to this post : http://www.alteraforum.com/forum/showthread.php?t=4035&highlight=error+while+creating+project+using+nios+ii+ide ) So, i've try copy my project folder into partition where it doest have any space character like this : C:\guitar_effect_processor_with _SOPC. but unfortunately it still give me the same error. any idea on this matter?
