Hi, I am unable to make any of my PIC work when I program it with my U2 usb programmer.
I compile it with MPLAB>>PBP.
Programs as simple as HIGH portb.7 : pause 2000 : low portB.7 are not working as well though the programmer shows that it got programmed fine.

Many times I have to disconnect/reconnect the wire of the USB programmer because of the error messeges such as "Device Not Blank........" or "Device does not match......" even though the correct device is selected. Is my programmer at fault?
Can someone please help me to know where the problem is? Thanks
