Using AMAKE purging utility

I am trying to get my uVision2 project to run on the PDS51E. I came across a document that says to try this AMAKE purging, but I don't see how to use it. If I click on the executable, it runs something and closes. The error I was getting when trying to load the .OMF file (no extension in uVision2) is:
'File contains unknown header record (02).'
So will this AMAKE purging help me? And if so, how do I use it?
Thanks
