Well i didn't had any bad chip as now. And it's not because i didn't wanted

I'd some bad experience, but as Melanie said, i set Erase before programming... and as now (finger crossed) i never had any bad experience. MAYBE a programmer problem. I don't have the EPIC so can't really be sure of it.

Is this the serial or the parrallel model?

If it's the parrallel, I saw kinda patch about XP printer polling blah blah...

Same problem on another Computer?
