At some point along that chain of objects, the object in question is not the thing that the library you're using thinks it is. This could be GeckoWebBrowser1, its Document property, or its DocumentElement property, or that's TextContent property. One of those things didn't respond to a COM call the way that code expected, so it threw this exception. You probably found a bug in that library. Or: you might be doing something earlier or later than it thinks. You'll have to ask whoever wrote that library, it's not widely used.
