LPC2378 beginner problem

I just bought the OLIMEX LPC2378 board and I am trying to start with the flash program provided and I can't get it to work
I am using windows vista , eclipse
what I do is the connect the openOCD via USB and open the project and main.c

then I
1. Build the project (Project->Build All).
2. Switch to the Debug Perspective(Window->Show View->Debug).
3. Start OpenOCD program from Run -> External Tools -> OpenOCD

I get this message

$URL: http://svn.berlios.de/svnroot/repos/openocd/trunk/src/openocd.c $

then when I Start the debugger the get an error window saying
"Launching main.out" has encountered a problem

the details of the error is:
