When I open up the solution that contains SSIS packages created by a colleague, I get this awkward error that tells me nothing about what I'm supposed to do to fix it.
He left instructions to take all the "variables" out of the connection string in the dtsx file manually before opening up the solution. I have done that, now when try to view the package in the designer I just get an image of a red x and this message.
EDDIT: You cannot see any design elements, no tabs across the top to switch to errors or data flows. Just a gray center area on the screen with a red x, and the message, its like VisualStudio dies in the process of reading the dtsx file.
