Time Lapse Engine Errors

Hello everyone,
I have been lurking around this forum for a while because I have been interested in TL photography and I finally decided to give it a shot and try to put together my own motion rig. I am very new to Arduino and programming for that matter. I have an Arduino and I have been trying to get the Time-lapse Engine version 0.82 loaded but I get the flowing errors in the Arduino IDE and I am not quite sure where to go from here:
 
OpenMoco_Timelapse_Engine.cpp: In function 'void serial_write(byte)':
OpenMoco_Timelapse_Engine.pde:-1: error: 'BYTE' was not declared in this scope
As of Arduino 1.0, the 'BYTE' keyword is no longer supported.
Please use Serial.write() instead.
OpenMoco_Timelapse_Engine.cpp: In function 'void serial_write(unsigned int)':
OpenMoco_Timelapse_Engine.pde:-1: error: 'BYTE' was not declared in this scope
As of Arduino 1.0, the 'BYTE' keyword is no longer supported.
Please use Serial.write() instead.
OpenMoco_Timelapse_Engine.cpp: In function 'void serial_write(long unsigned int)':
OpenMoco_Timelapse_Engine.pde:-1: error: 'BYTE' was not declared in this scope
As of Arduino 1.0, the 'BYTE' keyword is no longer supported.
Please use Serial.write() instead.
OpenMoco_Timelapse_Engine.cpp: In function 'void serial_write(long int)':
OpenMoco_Timelapse_Engine.pde:-1: error: 'BYTE' was not declared in this scope
As of Arduino 1.0, the 'BYTE' keyword is no longer supported.
Please use Serial.write() instead.
 
I have been searching on these forums and can’t seem to find any solutions.  Is there something I am missing? Any help or suggestions would be greatly appreciated.
