I get error code 35 with EPM570 (Quartus II 9.1 web on XP, USB blaster rev C). I can't find any lookup on what the error code means. Why have unlisted error codes? How is the number assigned?

Anyway, I can read the device ID hundreds of times the same (correctly), but cannot program it. I've tried several power supplies, different programmers, always the same error code.
