Having problems with opening of files on student/academic version of Creo

Hi!

I have the student version of creo 3.0 at home and the academic version at my university. When i tried to transfer an assembly + the 5 parts in it to try at home it wouldn't open and just said, missing parts or that the file couldn't be retrieved. I did transfer all the files so i didn't forget any file. What can the problem be?

Thanks in advance
