If I remember correctly, Milkshape had a 30 day free trial period.  So thats not asking for a warez or illegal software.
And if version 1.7.4 I think didn't have any issues with modeling, as mentioned in this forum, I would not have asked the question.  I would have simply gone and downloaded the current version and registered it.  
So how is asking about a previous version and if it might be available wrong, given there is a trial period for use?
No disrespect is intended
