Issues with quiz results sending in ProProfs

We built a SCORM 1.2 file for our client using Stroyline 360. They use ProProfs for their LMS and are reporting that they aren't able to see quiz responses on their end. I'm unfamiliar with ProProfs and don't have access to their LMS and have received no helpful information from ProProfs support. Is anyone familiar with this set up and can provide guidance on how to configure my Storyline file to send responses to their system?
