Pin 3 - write protect. I think bad contact with a programmer. Try to lift pin3.

It is not problem protection on chip, for sure, problem can be bad selection in software or some adjustment in software. But if you can not find what problem is, use another programmer. Like XPROGM, SEEprog, Ponyprog, Beeprog or similar. Or try to select another manufacturer in software.
