When you updated, did you happen to confirm you were adding the WAC, Sectional, TAC for that area. It seems like maybe you don't have all the charts for that area. If a sectional is "not installed" it will not install or update it automatically. You will need to check those charts on the update manifest. You can also confirm if they are loaded on the Chart Expirations page found by touching Menu and About. If this doesn't help, give our support team a call on Monday, please.
