SugarChimp

Hi, My Sugar campaign that was feeding one of my mailchimp lists via SugarChimp has disappeared. I can get Sugar to restore a backup of the database, manually extract the campaign database and import the data into the live database - which sounds convoluted and costly as opposed to creating a new campaign. I have created a new campaign but don't have the option to use the mailchimp list in the configuration settings. It only displays 2 of my mailchimp lists and I currently have 7. Can you tell me the best approach? Do I either delete my existing mailchimp list and start from scratch or get the database backup and restore from Sugar is there another way? Appreciate your advice.
