What exactly is the error message and what are you trying to convert? Maybe we can help you, and if not, maybe Norbyte can ;p
Well the current exporter is only a temporary solution until a custom one is made.
Can 3ds export to .DAE, and does it export skeletal meshes properly? If so, I'll look into writing a proper .GR2 <-> .DAE converter. Mmost other mesh formats are either proprietary and/or undocumented (like .FBX) or are incapable of storing skel meshes or other relevant stuff (like .OBJ)
