Students

When I try to open a company file it gives me a pop up box that says "only companies created in the student or educational versions of Sage 50 2015 can be opened in the student version of Sage 50 2015" How do I fix this?

I have installed, deleted and reinstalled at least 6 times (from disc and online) and I am unable to open the software. I have homework due in 3 days and need HELP!!!

For two weeks now I haven't been able to access the student data files to do my work. My instructor act like she can't help me. Can anyone tell me how to do this.
