Importing to Moi3d

I have a model I need to import into Moi3d (v3!)
I have it in .obj, .stl, .3dm & .fbx formats. - yes a CGTrader purchase
I know the 3dm format is native to Moi but all I get upon opening them is a few curves & meaningless solids - nothing useable. (I'm assuming they're rhino models - I often have this issue with those )
The ImportOBJ & STLimport scripts result in either Moi closing or nothing at all - I've been all over the net trying to find ways to convert a binary .stl file to ascii - no dice. Using the '_importobj exact" didn't work either

Any of you seasoned pros have a workaround? I'm not too worried about surface smoothness/resolution as I can probably do that with SubDiv

Any help appreciated ;)
