Help urgently please!

I'm running behind on a project and am having some problems with programming.

I thought I'd try out the PIC16f722 as I need capacitive buttons , have never used the device before. However I cant get my programmer to detect it. I'm using PICKit 2 program with a programmer by ETT called ET-PGMPIC USB I assume it's just a copy of the microchip one - as it uses microchips software.

I've tried my old chips on it - ie 16F88 and it detects those fine, however it will not detect the PIC16F722 - it just comes up with "No Device Found" if I try and read it, it says "Unsupported Part (ID = 1880)"

initially I tied it in the ZIF socket but it didnt work, so then I tried it ICSP mode, still nothing. The Vdd goes to around 6V for 100ms when I check communication - so it's getting enough voltage.

Anyone programmed this series of chips? Is there anything Im missing? I updated the operating system on PICKit successfully thinking it may have been outdated but still no joy.

Any help as always would be greatly appreciated.

Thanks
