That sounds like a configuration conflict issue.
There are a few things to try out.
Do you know how to get to your configuration folder for Blender? If so, make a copy of your 2.78 folder, and rename the original folder to 2.78-backup. With the folder renamed start Blender, and enable the ZB addon only. This will allow you to start with a fresh config, so you can try again knowing there is nothing that can get in the way. If all is well, you know it has to do with your current configuration, or enabled addons.
If you still have issues, open the console in Blender with Window > Toggle Console (Windows), or start Blender from a Terminal in OSX with:
Once you have a console to output to export again, and see what errors are sent back to the console. These errors will tell you exactly what is happening.
