Doh! I forgot to make the changes to global.asax when I upgraded from 2.0 to 2.11. Now that we have that out of the way I can show you the error I'm getting:

In RunnableProvider.cs an exception is thrown at line 47 for the EmailCampaignTaskProvider. The description is "Column 'templateName' does not belong to table Table."

Compare the sproc starting with DSC_EmailCampaign_* between the 2.0 and 2.11 if see if you have all the sproc updated. If that doesn't fix this, please post back entire the exception stack.

Yep. DSC_EmailCampaign_GetAllForSending and DSC_EmailCampaign_SendToMailingList were different. That resolved the error I described but revealed another. I won't bother you with the details of the error until I'm sure my entire database is up to date for version 2.11. Is there a change log or something that describes the differences between a 2.0 and a 2.11 database? I would rather my existing database than create a new one since we have store and customer data we would like to preserve.

I've checked my tables and sprocs and believe they are all up to date for 2.11. The error I get now when trying to start the orderpipeline is in runnableprovider.cs line 47 again. This time it says "The parameter 'address' cannot be an empty string." Here's the stack trace

Sorry to take up so much forum space with my problem.

The email address was empty. Run the sproc "DSC_EmailCampaign_GetAllForSending" manually and then figure out why some records have empty email address.

The sp executed normally and showed email addresses for all users. I did have an email campaign that didn't send because the orderpipelinecontroller wasn't set up to run. I deleted that campaign and now the orderpipelinecontroller seems to be starting alright. Thanks for your patience.
