Help on lCD and PIC18F4550 setup

[tacbanon]

Hi, sorry to post this beginner question, but I'm having trouble displaying text to the LCD with Pic18F4550 on 4Mz..
Code:

Define OSC 48      ' Core is running at 48MHz

Define LCD_DREG  PORTB
Define LCD_DBIT  4
Define LCD_RSREG PORTB
Define LCD_RSBIT 4
Define LCD_EREG  PORTB
Define LCD_EBIT  4
DEFINE LCD_LINES 2 		' Set number of lines on LCD
DEFINE LCD_COMMANDUS 2500
DEFINE LCD_DATAUS 250

   ADCON1 = 15          ' Set PORTA and PORTE to digital
   Pause 100            ' Wait for LCD to start up

mainloop:
   Lcdout $fe, 1        ' Clear screen
   Pause 500            ' Wait .5 second
   Lcdout "Hello"       ' Display "Hello"
   Pause 500            ' Wait .5 second
   Lcdout $fe, $c0, "World" ' Move to line 2  and display "World"
   Pause 500            ' Wait .5 second
   Goto mainloop            ' Do it forever

   End

Attached is my pin connections on easypic6
I'm having doubts with my LCD Settings, and how can I make it work using 8Mz crystal?

thanks in advance,
