Older mathcad files to Prime 8.0

I am a student and have already used the 30 days of trial for Prime 8.0 I need to convert a template from my professor that is an .xmcd file.  I cant convert it because I do not have the full version and I am not about to spend $60 to convert one file.  Can you guys help me get this file converted so that I can open it on Prime 8.0 please>
