A_en is 'X' problems

Hi, Ben

Unfortunately, i didn't really "solve" that problem. I don't know what i may messed up something during the project. i just delete the whole project except the source code which i 've wrote, and regenerate it from the very beginning, and the error is gone. i don't know, maybe you should try this, but before you delete anything, i suggest you check your development process according to the Altera Handbook carefully.

i hope that can help you.

best regards
