download this exe or run a clean install of your version (this is just the one you have - beta 05 b28:
http://www.geocities.com/vasudanad/modv32b5.ziprun it and fully install it, then paste the exe Raa Tor'h pointed you at and put that over the one in the modview install directory. once that is done you have the upped limits version all set.
however, that error is one that will crash fs anyway, if it is the case and not modview.
triangulate the entire model - debris, lods and all and see if that does it. if the error is still there, then it means that you have a single vert as a part of more than 20 separate polys. most often occurs with oversmoothed cones, or really complex parts. remove some of the faces to get the number under 20, and re-convert.
as for the model, use the original orion's trim. not the one you currently have from the arcadia. also fix the rightmost antenna with the texture to match the others (and align the textures uv projection a bit better on all of them), remove the streatched vent texture from the front and the rear side extrusion and replace with either better fits of the current texture or a different texture alltogether.
also add detail to the large polys of nothingness (on the underside, high on the righthand side, and down the back). it could also do with more interesting engines, and good versions of the orions turrets, such as the higher poly ones raptor made, or _something_ else. and finally put some trim around those strange blue and grey lights above the hangers.
