Welcome to the E-Learning Heroes community, FSI UPS! We're glad you're here.
I'm sorry to hear about the publishing issue, and I appreciate the troubleshooting you've already tried. It seems to happen with multiple courses, so we can start troubleshooting by checking if you're working on your local drive. Working on a network drive can cause erratic behavior. If the problem still happens, try these steps to fix possible installation issues.
If these don't improve things, could I have you connect with us in a case so we can dig deeper into this problem? We'll reach out soon after we hear from you.
