Thank you for you help.
I tried. The code can be complied under MB Pro 3.8, but it doesn't work. ( this project setting works for MB test code).

program SERVO8_USB
'******************************************************************************************
'* 18F2550 PIC USB_HID 50Hz PWM SERVO CONTROLLER *
'* by W. Schroeder alias "xor" -- July 4, 2006 *
'* Revised on September 25, 2006 *
'* *
'* Compiled with mikroBASIC 5.0.0.1 and tested on the EasyPIC3 Development Board *
'* Uses mikroBASIC USB_HID Library and must include "USBdsc.pbas" and "HIDconstant.pbas" *
'* *
'* Also required is the free Visual Basic Servo Controller Demo program included with *
'* this file. This program has been tested on Windows XP with USB2.0. *
'* * *
'* Configuration settings for the 18F2550 are the same as the mikroBASIC 18F2550 HID *
'* example found in the mikroBASIC Examples folder in the mikroBASIC directory. *
'* These configurations are set up for an 8MHz crystal oscillator and through internal *
'* PLL settings this is increased to 48MHz. This also produces a very fast 12 MIPS. *
'* *
'* The EasyPIC3 board provides an easy connection to the PIC via a USB port. Please *
'* refer to the board schematic for ideas for your own circuit connections. *
'* *
'* For the purposes of this demo all output pins of PORTB are utilized. *
'* Servo[0] is PORTB.0, Servo[1] is PORTB.1,...., Servo[7] is PORTB.7 *
'* *
'* The range of PWM on-time is 820us to 2180us analogous with values of 1 to 256 *
'* A value of 128 is considered 50% of servo rotation with an on-time of 1500us *
'* Timer0 in 16-bit mode is used to establish an accurate 20ms (50Hz) PWM interval *
'* *

Thank you.
Had to find the right settings for the Configuration Bits under edit project. 
now all my previous failed attemps seem to work. I just mirriored the ones from the example
Thanks
