Automation Exception

Discussion created by on May 19, 2012
I'm receiving "Automation Exception 0x8004035a" intermittently when I try to open a map such as:

AutomationException: 0x8004035a -
at Source)

For code such as:

md = new MapDocument();,password);

It's encountered in various places in my application and there doesn't seem to be a pattern to it.  Can anyone explain what this exception means and why it's breaking?
