URGENT help needed! Run-time error '380'. Invalid property value
I am using Articulate '09 update 4. I wanted to change one of the quiz properties on the quizzes in a larger course that I have used for a long time. I was able to change the properties for all until I got to the last quiz and then I suddenly got the above error message, preceded by the label "Articulate Presenter UI". I tried closing and reopening the file, restarting my computer completely, and even deleting the ppta file. Now, every time I try to open a quiz or an Engage interaction, I get the above message or the following:
"Critical Error: Could not initialize Insert Engage Interaction dialog" or
"Presenter was unable to open project file"
Also - I tried opening another Articulate course in PPT and accessing the quiz and I got the same messages. I realize that the forum states that this error was resolved with a later update, but I need to know if I can fix this without the update.
Any help is appreciated - I am on a deadline!
