I currently have 3 campaigns that I've created; one has no scripts (a campaign planned for the future), one is my testing ground for developing scripts (currently contains 1 script), and one is for an actual campaign (contains 4 scripts). When I created this topic, both campaigns with scripts were reporting the problem (the campaign without scripts is reporting that it's got no scripts, as expected). Since then, the testing ground campaign has started working again, but the sandbox for the actual campaign is still shut down, despite activity from multiple users. EDIT: Finally, after three days, the sandbox started up again. I've no idea what went wrong. hopefully it doesn't happen again.
