Sounds like you don't have adobe flash plugin (I'm assuming you are using Firefox browser?). Go to: https://www.adobe.com/software/flash/about/
to see if flash is working.
You should be able to get flash from the software center (or whatever zorin calls it). Look in your menu and somewhere it will say something like "software center". Then search for adobe flash and click install.
In Ubuntu (which zorin is based off of) they have "restricted extras" in the software center. That includes: flash plus a few other things like Mp3 support. You can also look if they have that instead (you probably want it).
