I frequently get this sort of message when just opening an existing data job:
An error occurred. Please contact the system administrator with the following information: Session Id: ac1dc293-dbb1-41bb-9d6e-dca5a61200c3
Mostly it doesn't seem to matter - I can run or finish the data job anyhow. Sometimes there are other errors, but there's no way to tell if they're connected to this one. What is this error for??
