Kevin i'm having the same issue on a 64bit machine
When i load my BIDs project i don't see an option to select the Sharepoint List Source and Destination in the Data Flow tab.
Also i had an old package that i believed didn't have the SPCRED (which i believe is was for sql server 2005)option and it was working before.
Now when i installed the new adapters and try to load the package in sql server to schedule a job i get error:
The package failed to load due to error 0xC0010014 "One or more error occurred. There should be more specific errors preceding this one that explains the details of the errors.
This message is used as a return value from functions that encounter errors.". This occurs when CPackage::LoadFromXML fails.
Can you help please
