Error on "Continue to next exercise"

[tchilds]

I'm using the Cloud version in a school. We've set up courses for our students; when they finish an exercise and click on the "Continue to Next Exercise" an error message pops up.

Custom Exception.
Access Violation.

You can return to the home screen and select the next lesson as a work-around.

This is an all-Mac school.

HI,
We have found the reason for this problem. It seems to happen only with user-made Courses where modules mix different activities. An update will be uploaded as soon as possible to fix that issue.

Fixed! Thank you, works great now.
