Backward Compatibility

Hello, I have SW Student Edition 2014-2015. I got a SW Education Trial Academic Year 2015-16 and used it to modify some of the files I made using SW SE 2014-2015. Now that the trial period has ended, will there be compatibility issue if I try to use the files modified using 2015-2016 on 2014-2015?
