Thank you for the fast response. I installed all the sugar customizations and the campaign summary reports are functional. The license key was successfully validated. I have performed the following steps:
1) With 4 lists in Mailchimp - I created target lists in Sugar that were empty
2) I mapped the custom fields (there were 3)
3) I specified to re-queue the sync in the custom fields.
4) I verified that the scheduler was configured. On the schedulers screen Sugarchimp's interval is every 5 minutes and the range is 1/1/2005 to perpetual - it is active. There is NO run history
5) Health status indicates that the 4 target lists are under list sync status and status is mailchimp to sugar queued
