Mike, I think I recall that Phil indicated in one of his postings a while back that Quartus II Programmer v11 didn't work for him and he had to go back to v10. I suggest using v10 (or earlier) of Quartus II Programmer a try and see if that doesn't cure your problem. I am still using v9.1 sp2 and it works fine. 73, Joe K5SO 1317508406.0
