Make sure you commented out the _config statements in the 18F4550.inc file and resaved it. If you don't the _config statements in the USBDemo code will give this type of error. I don't have any ideas as to the other error...sorry!

What is your development environment?....editor (MicroCode Studio, MPALAB or what?)...assembler (MPASM or PM?).....programmer (PicKit2, EasyPic or what?)
