For those of you who have noticed corrupted downloads lately, can you please try them again and report back on whether they're now working or not? I think we may have found a temporary workaround to the problem within the site code. If so we'll continue to pursue a solution but at least downloads should be working properly.
Ok. Unless some cosmic event goes horribly wrong I think we've plugged the corrupted downloads problem permanently this time. Please don't hesitate to report otherwise if they're still broken.
