Actually could YOU be more specific? It is very hard to diagnose a problem when all we have to go on is that you exported "it" and "it" reports an error. Some specifics which would help include:
Describe the model in detail (eg. is it animated? what are you using for texture?)
What command/code is producing the error? Run the code with debug on to find out. If it isn't too long post your code so that we can see if something is wrong.
*****
In all liklihood the problem is simply incorrect code. The path from Milkshape to Blitz3D is so simple there are very few places you could have made a mistake exporting; you literally just export from Milkshape to b3d and then use LoadMesh (LoadAnimMesh if the model is animated) in Blitz.
