Hi @LinBee64 and @Debbie-Rees,
For your information, we follow the standards and ActivePresenter SCORM files work well on well-known LMS.
However, as you may know, there are a lot of LMS in the market now. Some are set up differently and don’t follow standards so it’s hard for ActivePresenter can support it.
Since we don’t have an account on ESR so we cannot help to check the issue.
Please contact to ESR LMS support team for further suggestions.
Besides, you can check if that LMS supports SCORM 2004 or xAPI. If so, you can try exporting and uploading your package again since ActivePresenter also supports exporting projects to SCORM 2004 and xAPI along with SCORM 1.2.
Hope that it helps.
Thuy
