First I tried to remove a data viewer which caused BIDS to crash and tell me that VS has encountered a problem and needs to close. This is repeatable every time I try to remove the data viewer or the link or the entire data flow.
I also deleted the faulty package and created a new one by copying a valid package.
Even when I try to modify(delete) something from the newly created package the same problem occurs.
Any ideas on what to do to get Integration Servies working again?
