When trying to import a SCORM/AICC to a course, I receive a popup saying:

validation result:

Then when I clear the popup, the next page says:

There are some problems with the given package. Check it and try again.

This didn't help me determine what was wrong with the package, which passes all ADL tests and was made with Reload. I looked in my moodledata directory structure, and several directories from the SCORM package zip file were completely missing. I manually unzipped the package and pointed moodle to the imsmanifest.xml file, and the package now works fine.

I've seen a similar bug here, marked resolved. It would be helpful if the unzip process moodle uses addressed these issues, or the import process provided much more descriptive error messages about the nature of the import problem.
