I have been working on the same form for several weeks (In Livecycle 8.0). Today when I went to open it, I get the error message "Library returned system code 1, error 43. English text was "Expected an object Stream" " and the only option I have is to say okay, and the windows closes.
The Original Form was a MS Word Document that I converted to a pdf, and use Livecycle 8.0 to add drop down menus, fields etc. to it.
We have been using the form in reader for days, (testing it) and it still works fine in adobe reader, we can still open it without any problems.
However I needed to add more options to my drop down menu's and when I attempt to open the pdf file in Livecycle, all of sudden I get this error, system code 1, error 43.
I have googled, it a didnt find any help, and I have looked / searched the knowledge base with no luck.
