Solidworks Student edition 2013-2014 Question

Hi,

I've just installed the Solidworks Student edition 2013-2014. With it I am able to open files from other users with Solidworks Student edition 2013-2014, but I am unable to open a file from a used with Solidworks Premium 2014. It says "Cannot open... Future Version". It seems to me like since they are both 2014, they should be compatible?

Thanks
