If someone else created the campaign, you might be out of luck. The best bed would be to ask the GM of the campaign to let your rejoin long enough to export your character to the campaign vault. As a long shot, you could ask roll20 for help, stating the name of the character, campaign and username of the GM. Cotact them at <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a>.
