Upgrading database to 3.7 doesn't match entity model for 3.7 [Resolved]

I just upgradedfrom nopCommerce 3.3 to 3.7 using the upgrade scripts.  All upgrade scripts ran perfectly with no errors.  

When I run the website, I get an entity framework error.  Apparently the entity model does not match the upgrade scripts?  Did I do something wrong or is this a known issue?   Please help, thank you.

These were the messages I got in the exception:

{"An error occurred while executing the command definition. See the inner exception for details."}
{"Invalid column name 'LeasedByMachineName'.\r\nInvalid column name 'LeasedUntilUtc'."}

The error occurred on ScheduleTaskService.cs line 88 in nopCommerce 3.7

Update: Solved.
Be sure after you upgrade you're pointing to the newly upgraded database and not your previous copy of your old database.  Gotta remember how nopCommerce uses the settings.txt file for the database connection string.
