Just out of curiosity, why do you think there should be a special technical support section for students? The student version of the software is extremely cheap (if not free), unless I'm mistaken. Is that not benefit enough? You deserved dedicated technical support, too? Did you try filing a service request (via the little help menu in the top right corner of the Revit window)? In my experience (both as a student user and a commercial license user), they've been quite prompt in responding (24-48 hours, max).
Your person objections aside, could you elaborate on the problem you're having so that the Revit forum community (of which Autodesk is only a part) can offer our assistance? We've almost all lost a file at some time or another, due to any one of a number of reasons. If you could describe what happened, perhaps we can come up with a solution to resurrect your file and prevent it from happening in the future.
