| PIC18F2455 USB Problem / problem with programmer too |

Hi All,
I am using a ART2003 programmer which is specifically targeted to the PIC18F2455 chips. If I use a simple C program then WINPIC800 will load up the program to the PIC fine, but as soon as I try to convert any of the USB examples, by changing the h file to be for the 2455 then it complains about an address reading different to what has been programmed.
Is it possible for some kind soul to send/upload a reasonably complex non-USB program compiled for the PIC18F2455 and also a USB one they known to have worked with the above chip? This will help me debugging what has happened
Heres hoping

Solution found, my programmer is a low voltage programmer, and the defaults in the examples have the NOLVP fuse set :P so I change that fuse to LVP and all is lovely.
