Help with rgm to obj

Can somebody help me out to export this sdkfz 11 model from Company of heroes to obj file format ?

download:

My 3ds max script “rgm exporter tool” I used with 3ds max 9 work with alll other rgm files from COH but shows me “all meshes x reffed rgm” with this model !
Thank you !!!

Need this model for my free Order of Battle - Africa mod. Looks better like my own build !

No help here ?
