Ok..I can't download your schematic but here's some hints.
If you're using RS232 to the PC ,you'll need a max232 or similar device between the PIC and PC but since it's the 4550 I'm thinking you're trying to use the USB peripheral.
If so,start by using the CCS supplied USB CDC example program located in the examples folder.I know it works with a PC with XP. You do have to get the hardware right...it's common to swap D+ and D- ,could be a wiring error.
You don't say what your problem is
1) have you got the PIC able to run the '1Hz flashing LED' program ? That will confirm some hardware, fuses,clock speed etc.
2) then try the 'hello world' program if using the UART.
3) use the CCS examples and report back what's happening.
