Resend... Interestingly, I had this problem too at the start, and though I cannot remember what fixed it, the Tait SW had an option to NOT read during programming, and that did the trick for a while.

I am using pic_up (picup v1 by Tomas Franzon) software downloaded from www.admittansen.studorg.liu.se. After programming 16F84 a few times you can not program it again b/c it gives message 'PIC code protected' (Although code protection is not selected).
