System.NullReferenceException was unhandled

2
i am receiving this error on a working VB.net project immediately upon trying to run it in debug. Last week this program ran just fine in debug mode, now unchanged, it (and other projects) are giving me this error. Obviously it has something to do with my Windows/framework environment. Anyone have any ideas on what to check? Here is the detail error: (thanks in advance)

System.NullReferenceException was unhandled

Answer my own question: Debug information was not being created - just had to change the setting that generates debug info and to clear the "Enable ClickOnce Security Settings". Not sure how these got un-set.
