I'm here to help. When going from an older version of our software, such as in your case to a recent version, it's best to upgrade the file in small increments. So, for instance, upgrading your file from 2004 to 2010, then to 2015, and so on until you're on the version you have now. To do this, you'll need to install each version on your computer temporarily and open your file in each. You can grab the downloads here.
