I have been through this tips page however I'm still getting this error. I got this error in two ways. First, when my agent job runs and it errored out. The agent job uses DTSX package. The DTSX package builds fine, no error. The same DTSX package works fine in another DB SQL Server. The second way I see this error is when I open up this agent job up, click on Steps and then at the bottom I clicked on the "Edit" button. It stalls for a while then this error window pops up.
