Problems with moving Simscape from 2014b to 2015b

I have a Simscape model in Simulink that takes block inputs as workspace variables and I call it in a script. At my school the campus computers have Matlab 2014b, but our individual licenses are for 2015b so I have 2015b at home and 2014b at school. When I put the model from my home computer on google drive and then downloaded it to the campus computer all the variables in the blocks were changed to default values. For example, the tire blocks had their tire force values changed to the defaults from my magic tire coefficient variables.

Has anyone else experienced this problem? Is there a solution, I just want to be able to save my work?
