Approval Response Unhelpful

I've created 2 widgets that were waiting for approval, just received a very unhelpful response:

Before we approve your widget, Wild Pockets Mineseeker 3D, there's something we'd like you to change.

Here's the comments from our staff:
Your widget's content is either empty or failing to load. Please ensure that your widget looks as you expect it to on the widget's Dashboard and resubmit your widget for approval into the gallery.

I've tested this widget on XP & Vista, Firefox and IE and all are working fine. What do I do now?

Thanks.
