about Radlink

Hi, everyone. I have some questions:
1. After my simulation via Radiance, how can I postprocess it via
Radlink? Once i convert a DXF file to a Radiance file in Adeline, it
seems that i can not open Radlink.
2. In the process of simulation via Radlink, system always tell me :
Could not open file: *.rlo. Why? what can I do?


Peace of Mind.
