I once did a working example for the NEEK board. It can be found in the wiki.  

 

Maybe the DE2 has too few RAM to allow for Microwindow / Nano-X.  

 

BTW.: 

 

You modified your primary post to to show only the relevant information: good.  

 

But you again attached a picture. It would be much more appropriate to just copy the text directly into the mail. So it can be larger than just a few lines the reader can move it into an editor program to search it, etc.
